Hey all sorry this is my first post but everything else I had problems with i was able to search and find the answer. I have a plug which looks like a computer plug under my dash by the driver door. Also I have a red wire that was electrical taped to the wiring harness by the previous owner spliced into. I unhooked the wire and everything is still working fine any ideas?

My opinion is that red wire is a Hot lead either off the battery or the fuse box. A few tj models, including mine, a 2000, have 2 hot leads off of the fuse box behind the glove for accessories. There is a red, which is always on, and a blue, which works off key in pos 2. Trace that red wire to see if its live, was most likely hot for a cb, fog light switch or something. The little computer port is for the mechanic scanner for the codes if i'm not mistaken.

touch your tongue to it and see what happens!

its probably a hot wire for some accessory the previous owner installed.

If it would be a hot wire what would be the purpose of it going to the wiring harness for the door and being attached to the white wire? I'm at a loss with what the previous owner was doing with it.

3 prong fog light switches need a hot 12v lead to light up
