Wiring a 1992 Dodge W250 Pickup Truck for a 7-Way and 4-Way

Question

Question:

I am trying to wire a 7 pole plug with a 4 pole side plug on my 1992 Dodge W250 pickup truck. Where do I run the wires from to the plug? Are they run from the front to the back of the vehicle? Or how are they run to the plug? What size wire should be used? If different sizes what size is used for what connection?

Since you do not have a factory trailer wiring you will need to start with a 4-way (if you do not have one). For that you would want the # C55317.

If you don't tow a trailer with brakes all you would need at this point to convert a 7-way is # 37185. This has a 4-way and 7-way at the connector.

If you do have a trailer with brakes instead of the # 37185 you would want to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product as well.

For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup.
