Video Transcript for Spectro Wiring - Wiring Adapters - 9653P Review

Today we're going to review part number 9653, this is the Spectro 4-Way Trailer Connector Car and Trailer End Loop. This wire will extend your wiring about 12 inches, trying to give you an idea here. Put a ruler on it. You can see it gives you about an extra 12 inches in length. It does have on this end here, this is just like your vehicle end connector would be and this would be just like your trailer end connector, so what you could do is on your trailer you could take your trailer end, plug it into this vehicle end connector, and then that would extend your trailer end connector out about 12 inches. That should do it for the review on part number 9653P, this is the Spectro 4-Way Trailer Connector Car and Trailer End Loop.

12" Car and Trailer End Loop - 9653P

Average Customer Rating:  4.8 out of 5 stars   (88 Customer Reviews)


Just what was needed to extend the connection for my trailer hitch light. Was able to hide almost all the lead from sight. It allowed me to easily splice two wires together so the light comes on for brakes, flashers and both turn signals.


I received the product after just a few days. I had many technical questions that were answered by a competent service person. The product arrived in great shape and I had reviewed their installation video so installation went very quickly and easy. My 2011 Chevrolet Silverado is equipped with a 7 pole connection so I bought their adapter to convert to flat 4 pole connection. That an the CR-017 led worked very with first try. I also bought the trailer hitch lock at the same time. All products are very easy to use.


etrailer had exactly what I needed, and my order arrived earlier than I expected! I would definitely recommend them to a friend.


Purchased the 12" extender for my trailer lights after I purchased a different vehicle and needed more length on the wires to accommodate the new plug. Ordered the extender and received it within a week. Worked exactly like advertised on the site. Everything plugged in and worked perfectly.


The product is fine, well made easy to use and functional. Only complaint is that this extension cable is necessary to make a light kit work with one of the hitch mounted cargo carriers that it is advertised to work with. Other than that frustration, this extension did the trick, allowing me to now use my light kit.

One year later and the product is working fine. The length of the wiring harness continu s to be the only negative. I have had to order a second extension to allow the lighting kit to fit to a different vehicle... But overall, I am extremely satisfied with the his product, and with my experiences with e-trailer.
Richard S - 08/17/2016


Still working perfectly after one year. No issues at all.

Still works perfectly, one year later!
John D - 11/18/2021


Just the little extension needed when the factory trailer wiring harness plug wants to pull out of the socket when making sharp turns. Better to have the extension on and the lights working, because nobody wants to get stopped by the law for lights not working when leaving the boat ramp after a great day on the water.


I'll cut these loops in half and then solder and heat shrink them to the 4 wire cable. I'm making 2 harnesses, thus the reason I ordered 2 loups.

no problems

I'am in the process of setting up my 2017 Equinox to tow behind our motorhome. I've placed 4-orders with etrailer. So far I've installed the base plate, the wiring from the rear tail lights to the front end.I also received my Tow bar and the quick release parts. my next project is to install the invisi brake system. I want to send Kudos to Cathy T for her help and her great customer service. I'am also thanking James A for his quick response to a question about the wiring harness. I'am extremely happy with the quality of everything I ordered at etrailer. Thanks


I have purchased several items from etrailer and recommend all of them and the folks at etrailer.
Items purchased by part #: 9653P; BK-70BB; 2118-605-04; 98174LED; PK12706; MCL11AKB; H20046.

Shipped well packaged. All items are accurately described and are fully functional. etrailer videos are a big help and their staff is knowledgeable!


Love it ! Perfect to use, when hooking up "trailer lights" on cargo carrier to your SUV !
Easy to use & hook up ! Highly recommended !


Not much to be said other than it looks like a quality piece. I havent used it yet, ordered as a precaution for use with my hoppy trailer wiring kit incase the harness was to short.


Ordered Dodge trailer hitch cover. Was extremely pleased with the website and especially the video that I could watch before ordering. Video explained installation and any additional parts I might want to order. Very happy with product.


I joined 2 of these together to lengthen the wiring harness to connect the trailer to the car with a hitch extension that I used.


This 12" extension was just what I needed to connect a light up brake light hitch cover for my Ram truck. I bought one for my son's Chevy Colorado also.


etrailer suggested I also buy this extension for my light kit and I'm pleased they did because the light kit I bought would not have reached the outlet on the car if I did not have this extension.


This end loop allows me to keep the connections on the car and trailer short and out of the way when not in use. I can plug the ends together and fold it for storage when not in use. Works great!


It works. The cable was too short for the hitch cover to reach, this makes it long enough now.


Exactly like the original. Good quality. Shipped and received quickly. Easy installation.
Great service. Highly recommend etrailer.

I spent slightly more money on four items than I would have spent on just one part elsewhere.


Great extension if your trailer wiring is too short and a good alternative to cutting and splicing!


Perfect to splice into trailer hitch pl ug.


Everything arrived on time and intack.Easy assembly .Tail light trailer in loop was a must and tail lights a must have.


The 12" Car and Trailer End Loop made my wiring 12" longer to give more length off wire to work with.


Received 7 pole to 4 pole adaptor along with the 12" Car and Trailer End Loop in a very timely manner and it was exactly what I needed.


The products were fine. I think the extender cable should of been shrink wrapped so that the four exposed wires would not be seen.

Other than that the package arrived on good condition.

  • Light Kit Not Long Enough for the Railed Cargo Carrier
    If the trailer connector is tucked up under the vehicle, sometimes there is not enough wire for the connection to be made. We offer an extension, you can see the product by clicking on the link you'll find below.

  • Are Car and Trailer End Loops # 9653P and # 18044 Each One Piece of Wire of Two Pieces
    The Car and Trailer End Loop, # 9653P, is one l2 inch long piece, just as it appears in the picture. The Car and Trailer End Loop 4-Pole, # 18044, is also one 48 inch long piece. It comes with quick splices in case one of the 4-Way connectors needs to be clipped off to splice bare wires. You can see this harness in use at about the 2 minute, 58 second mark of the video linked below.

  • Parts Needed to Make a Brake Controller Portable Between a Toyota and a Jeep
    At this time we do not carry the vehicle side of the Brake Control Wiring Adapters for an installation application like you are suggesting. But, I do have a recommendation for you. You could use a 12 inch Car and Trailer End Loop, item # 9653P, and wire the brake controller wiring to this. You would want to attach the vehicle side connector, 3 protected poles and exposed ground pole, to the vehicle and the trailer side to the wiring from the brake controller. You would then need another...

  • Availability of 4-Way Square Connector for Wiring a Ford 3600 Tractor
    If you will be needing to connect and disconnect the plugs more often I would recommend just to remove the 4-Way square on each end and wire in the 12 Inch Car and Trailer End Loop, part # 9653P. You will just need to cut the # 9653P loop in half and wire each end to the wires that remain from removing of the 4-Way square connectors.

  • How to Extend a Trailer Wire 4-way by 12 Inches
    If I am understanding you correctly you have a 4-way on your 2012 Toyota Highlander but you are looking for a way to extend the wiring of the 4-way by 12 inches. What I would recommend you get would be a 12 inch Car and Trailer End Extension # 9653P. This product will extend your 4-way by exactly 12 inches and should work well for you.

  • Availability of Just 4-Way Connectors
    What harness are you looking for? Like a 4-way that comes on part # 002220? We have the part # 48195 as well or the part # 9653P that comes with both sides plus wiring if needed. You would just cut the middle of the wiring and would have wire for both sides.

  • Compatibility of the Light Kit # 20174 to work with the Pro Series Cargo Carrier # 63153
    The off-set wiring harness that comes with the light kit # 20174 is about 3 feet long and runs straight to a light and other lead wire is about 6-feet and runs along the back edge of the Pro Series cargo carrier # 63153 before it curves up to the 2nd light. The Pro Series cargo carrier # 63153 has a tighter mesh floor which is not large enough for the plug to pass through. Therefore run the wire leads under the platform to the lights, then up the front of the carrier and around to the...

  • Isolating Power for a 5-Wire Motorcycle Trailer Harness and a 5-Wire Motorcycle Trailer
    There is a way to isolate the power draw on a 5 wire to 5 wire setup, but it would require a few parts and some wiring work. All of the isolated power trailer converters convert a 5-wire vehicle to a more standard 4-wire system for automotive use trailers, but as you are aware, motorcycle trailers are built as 5-wire systems to match the bike. You would use part # 119147KIT on the bike. This part has 5 wire leads to connect ground and the different light functions. The 6th wire is the...

  • Installing MaxxTow # MT70097 Magnetic Mount Tow Lights Permanently on Vehicle
    The Peterson # PE26UR Magnetic Tow Lights could be modified by doing some cutting and splicing to work as you describe. You would attach the connector of the wiring harness at the front of the vehicle and run the wiring under the vehicle. Following the frame member or an existing wiring harness works best. Run the wires to the rear of the vehicle, being sure to avoid any suspension and steering components that might move or anything hot like the exhaust system. Under the vehicle at the...

    We do offer a 4-foot extension wire equipped with 4-pole flat vehicle- and trailer-side connectors, part # 18044 from Draw-Tite. If this is longer than you need we also offer a 1-foot extension, part # 9653P, which also provides the same plug-in extension capability. No cutting or splicing is required for either extension. I recommend an application of dielectric grease on all connections when you install your light kit. We offer this (part # 11755) but it is also available locally at...

    Best option for a 4-way extension for use with the # CR-007D would be the part # 9653P. This is a 12 inch long extension that will give you just enough extra wire without adding too much wire.

  • How to Make 12 inch 4-Way Male to 4-Way Male Adapter

  • What Parts are Needed to Connect a 4-Pole Trailer to a 5-Pole Motorcycle
    If your bike is a 5-Way flat wired like most vehicle 5-Ways, then you could just plug the 4-Way trailer connector in. Obviously the 5th wire will have no connection which is fine. If the bike is a 5-Way round, there currently not any adapters available. You could make your own adapter using part # PK11501 and part # 9653P. You could also convert the trailer to a 5-Way round using just part # PK11501 and again omitting the 5th contact point since it is not needed on the trailer. If you...

  • Extension Cable Available for the LED Light Kit for Railed Cargo Carriers, # 98174LED
    Installation of this LED light kit wiring, part # 98174LED, may vary slightly depending on the specific cargo carrier you have and whether the wiring harness to the LED light assemblies has to be run underneath the cargo bed versus being threaded through the carrier deck. (This will depend on how large the openings are within the deck material). I have included a video link for this product that you may find helpful. We do have both 12 inch and 48 inch 4-pole connector extensions available....

  • Parts Needed to Extend a 4-Way Trailer Connector
    You just need an extension loop like # HM47115 which is 48 inches long. If that is too long then we have a 12 inch extension # 9653P. If you want to make these extensions permanent then I recommend using some dielectric grease between the connections, # 11755, using zip ties to hold the connections together, and then using electrical tape to wrap it all up to protect it from the elements.

    I have a solution for you. We do not have any type of Y adapter but I do have the parts available to allow you to connect both 4 wire flat plugs at the same time. I do recommend that you first check to ensure that you will not be drawing too many amps on the circuit by using both the dolly wiring and the tow lights together. You will need the following products: Car and Trailer End Loop, # 9653P Qty 2 Pollack 7-Pole Trailer Connector, # PK12706 Qty 1 First you will start by cutting...

  • What Light Kit Will Work with the Reese Cargo Carrier # 63153 on a 2021 Toyota Tacoma?
    For taillight kits for the 24x60 Reese Cargo Carrier for 2" Hitches # 63153, I recommend the Light Kit for Draw-Tite, Tow Ready, and Rola Railed Cargo Carriers # 20174. On the Reese cargo carrier # 63153, the tighter mesh floor is not large enough for the plug to pass through. Therefore run the wire leads under the platform to the lights, then up the front of the carrier and around to the back of the light. This also helps prevent the wires from getting pinched by the cargo. On vehicles...

  • Wiring Harness for 2015 Land Rover Evoque to Connect to Lights on Bike Rack
    In order to connect the LED Light Kit # 98174LED to your 2015 Land Rover Evoque you will need a trailer wiring harness with a 4-Way flat trailer connector, such as the ZCI Circuit Protected Vehicle Wiring Harness with 4-Way Flat Trailer Connector and Installation Kit # 119250KIT. This wiring harness will install on your Evoque without requiring you to cut or splice into the factory wiring on your vehicle.

The LED lighting kit, part # 98174LED, includes the set of two 12-diode oval lights, rubber mounting grommets and wiring.

I'd highly recommend the # 98174LED light kit and the # 9653P 12 inch extension. Keep in mind that the # 63153 is only compatible with 2 inch receivers. Your cargo can be held in place with a cargo net or tie down straps, depending on what you're carrying. I've linked you to the straps and nets we have available.

    I checked your order notes and it looks like you ordered part numbers # 9653P, # HM48192, and # HM48190. It could be as simple as a bad ground that is causing the running lights to now work, but since the bulb was blown that would more indicate a short on the wiring of the circuit somewhere. Check the wiring of the circuit for any exposed or cut wire and fix as necessary. I realize that's the last thing anyone wants to do in the cold but that is most likely the problem.
