Recommended Replacement Trailer Wiring Harness For 2002 Dodge Ram 1500 With 4-way

Question:

I cant get any signals,rear lights , or brake lights on my existing Mopar wiring harness. Lights work fine on truck. I have been on this problem for 5 days at 8 hours a day and part nights. Heres what I want to do. I want to get rid of the Mopar Wiring Harness all together. Im fed up. I want the easiest regular 4 plug harness that I can put on . Dont need a big plug and cap. Just a rubber plug and with 4 wires. Ill fix the hole. I prefer a harness that doesnt have to be spliced. But right now Ill try anything to get my boat back on the water. HELP PLEASE. Thank you.

We have just what you need for a trailer wiring harness replacement. But you may want to first check the trailer wiring fuses or relays. You should have a fuse legend on the inside fo the fuse panel. You should be able to find it in the owner's manual or check with your dealership for the trailer towing fuses or relays.

You said you have the Mopar wire harness on your 2002 Ram. If you did not have a 7-way harness I recommend part # C55504. You just need to locate the connection points behind the rear bumper on both side of the truck. Plug in the connectors included with the harness and you will have a working 4-way connector.

The wire harness you came form is the Hopkins Tail Light Converter Kit with 4-Pole Flat Trailer Connector, part # HM48925. This is a hardwire trailer harness which you said you wish to avoid.

If your truck had a factory 7-way wiring harness I recommend the Multi-Plug T-One Connector Assembly, part # 20135.

This simply plugs into the connector at the rear of the vehicle near the drivers side frame rail above the spare tire. Installing this harness will give you a working 4-way and 7-way connector. This harness comes with a mounting bracket included.
