How to Install a Wiring Harness for a Trailer on a 2001 Dodge Ram 3500 Van
Today on this 2001 Dodge Ram full size van 3500 we are going to install part number 118381 from Tow Ready. This T-One connector is designed specifically to plug into the van with or without the OEM 7-way connector on the back. This is the connector right here and this van does not have the OEM 7-way connector. We are going to take off this cap right here and then go ahead and install our T-Connector. These little red blocks are what you want to undo first.
Push down this button back here and the cap should come off. Okay, do not loose the cap. What we are going to do next is go ahead and install our T-One connector back into the matching socket. And then go ahead and put the lock back into place. And take your cap which will go on the remaining half that is not being used. Again put the lock into that too. And then all you have to do is just zip tie our wires up and get them out of the way and run our 4-pull wire out to the hitch. Once you have everything connected and secured it is a good idea to go ahead and test it with a light tester first before you connect the trailer so you know the van is working fine before you plug into your trailer. And there you have it for part number 118381 from Tow Ready.

Great video, thanks. I have a 2001 Dodge 3500 van chassis fro my Leisure Travel RV. It has an OEM hitch installed and the same pigtail as in your video. Anyway, I installed CURT 57300 Dodge OEM Harness just like you did except mine was 7 at plug. Install went fine, but there is no power at connector—I used a CURT 7-Pin blade socket tester. When I looked at fuse box under hood, I discovered the “Trailer Tow Class 3 only” spot did not have relay installed. I tried to test by swapping adjacent relay (same part#), but trailer relay spot did not have contacts for the relay. Any ideas on how to proceed.? Thanks.
