Video Transcript for Spectro Wiring - Wiring Adapters - 9651P Review

Today we're going to be taking a look at part number 9651P. This is Spectro two pole flat wiring extension. It's going to measure 12 inches long. It's going to be a two pole positive and negative wiring loop so it's going to supply your ground and power. The cord can be cut into two compatible plugs. That way you can create a plug-in connection for a hard wire 12 volt accessory such as a backup camera, a side marker light, a license plate light, reverse light, something that requires a ground and then power for one function. It's going to contain 16 gauge copper wire construction.

It's also going to feature the tin-plated terminals. It's going to stand up really well against rust and corrosion. Again, you're going to have an overall extension or length of 12 inches. That's going to do it for our review of part number 9651P. This is the Spectro two pole flat wiring extension.

Average Customer Rating:  4.8 out of 5 stars   (14 Customer Reviews)


TRhese are Great! I used 2 to extend the line between the solar trickle charger and battery on motorized boat lift. Also during the winter to keep the battery charged with a smaller panel on a garage window sill.Just pay attention to the conveniently color-coded wires to maintain proper polarity


I needed two 12v leads to add backup lights to my trailer. Works great. Very tight connection. I cut it in half and connected one side to my trailers left and right backup lights and the other end to my truck.


This adapter worked great to wire up a license plate light on my cargo carrier.


Hard to find 2 terminal plugs except to cut them off an old wiring harness. Thanks for carrying them!


Excellent adapter…I cut it half to use with my removable removable fenders being I mounted some extra tail lights on them for more visibility, worked out great!


Product came yesterday in a very timely manner, product was exactly like it looks in picture, great quality and I have someone installing it as I type this. So a more in depth review later on when it is installed and I will send pictures. Also the staff at etrailer is awesome they do a great job with customer service!


Good quality material,very handy.I will use it to connect led marker lites to a removable truck bed panel.


Thank you, your website made it easy to find several items that i was looking for and delivery was quick.


As described, good connectors.


Great product !!!!!

  • What Gauge Wire is Used on the Spectro 2 Wire Loop # 9651P
    I spoke with my contact at Spectro and she informed me that this 2 Wire Loop # 9651P uses wire that is 16 gauge.

  • Proper Wiring of a Hitch-Cover Brake Light so it Does Not Blink when Turn Signal is Activated
    If you want your hitch cover brake light to only work with the brake lights, I would recommend that you use a 2 Wire Loop, item # 9651P, to make a separate connector for your brake light hitch cover. Then run the white wire to ground and splice the red wire to the third brake light circuit which does not blink when the brakes are applied and the turn signals are activated. You will have a separate two wire connector for the hitch cover with this setup. At this time I do not know of any...

  • Wiring a Backup Camera to be able to Move it from The Truck to the Trailer
    Typically, on a factory installed 7-Way, the center pin is for reverse lights. If there is not a wire in the center pin on the trailer side connector, you can add one and run it all the way back. I would purchase a couple of 2 Loops with connectors, part # 9651P. You can use these connectors to provide a quick and easy way of disconnecting the camera system to move it from the truck to the trailer. Depending on the camera system, you may only need the two wires, one for ground and one...

  • Amperage Rating of 2 Wire Loop, 12" # 9651P
    The 2 Wire Loop, 12" # 9651P that you referenced is made of 12 gauge wire which has a 13 amp rating.

  • Recommended Plug to add Lights to Trailer Tailgate
    In order to add lights on your trailer's tailgate that will allow you to remove it, you can use 2 Wire Loop # 9651P. What you would want to do is cut it in half and use one side for your tailgate and one side for your trailer. I've added a link to a video review for you to take a look at as well.

  • How to Wire Illuminated License Plate Holder to Trailer Connector
    To wire an illuminated license plate holder such as the Optronics LED # LPL55CB, you can simply splice into the running light circuit and ground wire from the trailer connector. I recommend using the 2 Wire Loop # 9651P to make these connections. This will allow for a quick and easy disconnect when you are not using the cargo carrier/rack on your trailer hitch. I have attached a couple of short video demonstrations on these products for you to check out.

  • Does Vehicle License Plate Need to Relocated When Using Hitch Cargo Carrier
    The legality of an obscured rear license plate varies from state to state. If you want to heed the letter of the law, the plate can be relocated to the rear of the cargo carrier. We sell quite a few cargo carriers, and to be honest, it is really not that much of an issue. You could zip tie the plate to your carrier, or use a bracket with a light like part # LPL55CB (In most states, the rear license plate is required to be lit after dark). If your vehicle has a trailer connector, you...

  • Can Extension Cord Be Used Between Solar Panel Charger and Battery
    The Performance Tools 2.5 Watt Solar Battery Charger # PTW2997 includes a 9-foot cord and both a cigarette lighter style and a spring clip style extension that plug in with 2-pole connectors like those on part # 9651P. If your battery tender's cord uses this type of connector then it will plug in and function but you'll want to keep in mind that the added 25-feet of wiring will cause some voltage drop. If you happen to have a set of heavy gauge jumper cables around, something like the...

  • Recommended Location to Attach a License Plate to a Tilt Easy Hauler
    I would recommended checking with your local law enforcement or state highway patrol because laws and regulations vary from state to state. On the other hand, I have seen a couple license plates mounted to the wheel fender. I would recommend a license plate frame such as # CR62032. It will show more plate in all 50 states. A LED license plate light mounting bracket such as # LPL55CB could also be a great addition especially since you are towing a easy hauler. I have included a video...

  • Replacement 5th Wheel LED Tail Light for a Round Red Light
    Thank you so much for your photos. We don't have an exact replacement light for you, but we have something very close. It's the Optronics LED Trailer Tail Light, part # STL13RFHXB. This LED light measures 5-5/8" in diameter (almost exactly what your current one measures) and has the three mounting holes. It features the 7 diodes that your current one seems to have and the same three functions. Most importantly, it's round and fully red. This is a flush-mount design, so there is a difference...

  • Matching Connector for the Optronics Trailer Taillights # STL36RPG and # STL37RPG
    For the Optronics trailer taillights # STL36RPG and driver side # STL37RPG we do carry the style of connector it uses with the part # 9651P. You'd cut the harness in half and wire either side to your trailer wiring so that you can easily connect to the lights mentioned.

  • Cargo Carrier, Light Kit, and Wiring Harness for a 2000 Honda Accord
    I will be happy to help you out. First, since all of the trailer hitches for the 2000 Honda Accord are Class I hitches you will need a cargo carrier that is rated for a Class I hitch. I have included a link to the available options for you. You will need to have a 4-Way flat connector on your Accord to activate a license plate light. If you do not already have a 4-Way you can add one using # 43105. Then you could use license plate mounting bracket and light # PM436B. The power wire can...

  • Wiring Compatible with the LED Tail Lights with SAE 2 Wire Connector
    The SAE two wire connect is sometimes a factory connection, but you can simply cut the connector and use butt connectors like # DW05744-5 for the LED Tail Light for Trailers Over 80" Wide - 7 Function - Submersible - 17 Diodes - Passenger # STL36RPG and driver side # STL37RPG if desired. If you want the quick connect, then I recommend getting the 2 Wire Loop, 12" # 9651P and cutting the middle to give you the two quick connectors you need for that lighting kit to have the quick connects...

  • How To Wire Light Bar On Trailer With Switch In Vehicle
    You can definitely install a light bar on your trailer and control it with a switch in your truck. I will say that it will require quite a bit of cautiously routing wires to avoid moving/hot parts and some splicing wires as you will have to extend the light bar wires to reach that far. I will use the Buyers Products Off-Road LED Light Bar 39-1/2" Long # 3371492184 for example. For this light bar you will need the wiring harness # 3373035768. You will need to install the switch inside of...
