So, I was not aware and didn't check when I bought my 2004 1500 that someone had cut out the factory towing harness. They clipped it off right where it splits off from the loop for the tail lights. Anyway, I went to a pick n pull, and now I have spliced back in the wires and plug (female plug). The end plug has a little half loop on it made of steel that must snap on something somewhere Does someone know where it might snap into? Right now I just have it laying on top of the spare tire.
