See what our Experts say about this Mighty Cord Custom Fit Vehicle Wiring



  • What Gooseneck Wiring do you Recommend for use with an In Bed Camper
    Yes we sure do. The Mighty Cord 5th Wheel/Gooseneck Wiring Harness w/ 7-Pole Connector part # A10-7010 is an excellent choice and offers the 90 degree turn to keep it from hitting the bed sides. I chose this one because the 10' length will give you plenty of cord with out being too short. When routing it you will be surprised how quickly 10' of cord disappears and any excess can always be zip tied up and out of the way.

  • 5th Wheel Wiring Harness for 2021 Ram 2500
    The 5th wheel wiring harness I recommend for your 2021 Ram 2500 is the Mighty Cord 5th Wheel/Gooseneck Wiring Harness with 7-Pole Connector # A10-7010. I really like this harness because Mighty Cord is known for making really durable and high-quality wiring products, and because it is 10 feet long to ensure you have more than enough length to reach your Ram's factory plug. In regards to install, if you already have a hole cut out, you won't need to drill another one. I have added a link...

  • What Gauge Wire Is The A10-7010 Mighty Cord Universal Wiring Harness for 5th Wheel
    The Mighty Cord 5th Wheel/Gooseneck Wiring Harness , # A10-7010 is all copper wiring, and it is 18AWG.

  • Required Mounting Depth For Mighty Cord 5th Wheel/Gooseneck Wiring Harness On 2020 GMC Sierra 2500HD
    The Mighty Cord 5th Wheel/Gooseneck Wiring Harness # A10-7010 requires 3-1/2" of clearance behind the mounting flange of the 7-way connector. This measurement includes the wiring connector for the 7-way connection. This will be your best solution as the other harness have similar connections and the magnetic EZ connectors require more clearance as the wiring does not 90 degree from the back of the connector like the Mighty Cord.

  • Recommended 7-Way Splitter for Second 7-Way Connection for Truck Camper
    We don't have a 7-way splitter like the photo you sent. We instead for applications just like yours recommend using the Mighty Cord 5th Wheel/Gooseneck Wiring Harness w/ 7-Pole Connector - 7' Long # A10-7007 or the 10 foot long # A10-7010. This will allow you have the connection at your bumper as well as a connection in the bed of your truck wherever you choose for a simple connection to your in bed camper. There is no problem with charging your battery for either or both of these connectors....

  • Trailer Connector Recommendation for 2005 Chevy Silverado Long Bed
    I'd recommend going with the # A10-7010 10 foot long version, as my fear would be that the # A10-7007 might come up a little short in length. I've linked to an installation video for the 7-way and wiring harness that you might find helpful.

  • Fifth Wheel 7-Way Wiring Kit Recommendation for 2000 Ford F-350
    We have the Draw Tite 5th wheel 7-way kit part # 20031 which is confirmed as a fit for your 2000 Ford F-350. It has the square connector you mentioned to connect into the vehicle wiring. The harness length is 7 feet though which is normally enough to get the connector up into the bed of the truck. For a similar setup that uses a 10 foot harness we have the part # A10-7010 but this ties into the wiring by wiring into the round connector behind the 7-way at the vehicle bumper.

  • Recommended 5th Wheel Hitch Rail Kit for 1994 Chevy 2500 Pickup
    I recommend going with the B&W Universal Base Rails and Installation Kit # BWRVR3200 for your 1994 Chevy 2500 pickup. This gives you the standard base rails that you need to utilize the Reese Pro Series 30056 15K 5th wheel hitch you have. If you don't already have a 7-Way connection in your truck bed I also recommend checking out the Mighty Cord # A10-7010 which tees in behind your current 7-Way using the US Car Connector plug. This wiring makes it easier to connect the wiring from your...

  • Compatiblity of Underbed Pucks and 5th Wheel Hitch for 2015 Chevy Silverado 3500
    For your 2015 Chevy Silverado, the Under-Bed Rail and Installation Kit for Reese Elite Series 5th Wheel Trailer Hitches # RP30868 is a confirmed fit. The Reese Elite pucks have the same dimensions as the Ford OEM pucks so the Reese M5 5th Wheel Trailer Hitch for Ford Towing Prep Package- Single Jaw - 27,000 lbs # RP30922 is a fit. The max capacity is based on the smaller capacity of the two parts so your max capacity is 25,000 lbs based on the under-bed rail kit. I also recommend you...

  • Recommended Curt Fifth Wheel for my 2018 Ram 3500 Prep Package
    For your 2018 Ram 3500 with the Prep Package the Curt Q25 5th Wheel Trailer Hitch for Ram Towing Prep Package part # C16049 is going to be the way to go. While the Q25 part # C16265 is very similar its legs are for industry standard in bed rails rather than the custom puck legs for your Ram and won't fit. These are both however made here is the USA. The Mighty Cord 5th Wheel/Gooseneck Wiring Harness w/ 7-Pole Connector part # A10-7010 will work out really well if you do not already have...

  • Auto Slider 5th Wheel Hitch for 2017 GMC 3500 Long Bed Dually with Factory 5th Wheel Package Pucks
    For your 2017 GMC Sierra 3500 Denali with long bed and dual rear wheels you can absolutely still use an autoslider hitch if desired. Since you have the factory 5th wheel prep package puck system you will first need the adapter # DM6206 and then you can use the Demco Hijacker 18,000 lb # DM8550034 or 21,000 lb # DM8550035. This will work very well together. You also may want to consider adding a wiring connection to the bed for a clean look and easy connection point using # A10-7010....

  • Maximum 5th Wheel Towing Capacity for a 2010 Ram 2500 with 6.7 Cummins Engine
    According to my research, a 2010 Ram 2500 with the 6.7L turbo diesel engine has a maximum towing capacity of 13,350 lbs if you have the manual transmission or 13,450 lbs if you have the automatic transmission when properly equipped. Therefore, I cannot recommend you use this truck to tow a 15,000 lb trailer. If you are able to find a trailer that is within your vehicle's towing capacity then you will need an installation kit and 5th wheel hitch in order to tow it. For this, I recommend...
