Review of Custer Wiring - Wiring Adapters - ADP7R-7B Video

The overall length of the Ram Gooseneck to 5th Wheel Trailer Coupler Adapter - Round - 30K item #KPG5-R30IP is 29". It is 14" from the top of the tube to the first adjustment hole. I have attached a diagram detailing these measurements.

I attached a picture that shows the Torklift Camper Tie Down #TLF2021 installed on a truck with a set of running boards. If the running boards are cab length they'd be fine, but if they go from the wheel well to wheel well they would interfere as…

In order to haul your gooseneck trailer with a fleet of semi-tractors you will need to make your own adapter harness which will then make for a plug and play connection but they don't make anything pre-assembled for this out of the box to my…

You can use the Pollack #PK11700 to install on your gooseneck trailer and create a 7 way plug capable of fitting on the 7 pole round plug that is on a semi tractor trailer truck. For the wiring you can use the Deka Jacketed 7 Wire #DW04914-1 which is…

The 2-5/16 inch hitch ball with the longest shank that we carry is the #BWHB94003 which has a 3-1/4 inch long shank that is 1-1/4 inches in diameter.

As your 7-Way pin connector uses separate turn signals and brake light wiring you will need the to create a custom harness to be able to have everything function properly including the electric brakes. First you will start with the Pollak Heavy-Duty,…

The Curt Echo Trailer Brake Controller #C51180 needs to have a 7-way blade connector on both the tow vehicle as well as the trailer. The Custer Trailer Connector Adapter #ADP7R-7B that you found is designed to adapt a vehicle with a 7-way round pin…

There are a number of factors involved when converting a semi 7-way to an RV 7-way. Semis generally use a 7-pin round pin socket, similar to #PK11720. And RV style 7-way uses blades, like #PK12706. We do not offer any pre-made adapters to make this…

Either way is correct. It depends on if you want to keep the semi-style 7-Way (if you need to tow that type of trailer) or if you will never be towing a semi-trailer. If you need to keep the 7-Way semi active on the truck, then you would need to make…

I attached a diagram that shows how most 7-way rounds like the #PK11720 that you referenced will get wired up. As long as you got yours wired up correctly and your trailer taillights and brakes are functioning correctly that's all that should…
