The wire that runs from the vehicle's battery to the 7-way trailer connector and then from the 7-way trailer connector to the trailer battery should be at least a 10 gauge. If you don't have any 10 gauge wire you can purchase part # 10-1-1 by the foot. Please note, you will need a circuit breaker part # 9510 on this charge line wire about 6" away from the battery on the tow vehicle. The 7-way trailer connector can then be used to attach and disconnect the charge line between the tow vehicle and trailer.

I recommend using the Roadmaster wiring for your 2024 Ford Maverick because I've found it to be the most reliable on the market. The correct kit depends on if your Maverick has LED lights or not: - LED Lights #RM38FR - Non-LED Lights #RM-15267…

If you have a vehicle specific wiring harness for a brake controller then that would indicate that you have a factory tow package and subsequently would already have a 7-way at the back of your vehicle. The universal 7-way connector #ETBC7 is meant…

With your 2012 Ram 1500 I would definitely steer towards a standard bumper pull trailer. Generally speaking, 1/2 ton trucks just aren't really built to pull a 5th wheel trailer, as they are typically heavier and will put more stress on the rear…

The wiring that comes with the 7-Way RV Upgrade Kit #ETBC7L is only meant to carry the 12V power for 1 function. Since you're wanting 12V power from your vehicle battery to go to 2 functions you need the Universal Installation Kit #ETBC7 instead.…
