I have a 1977 Dodge Ram 1500 with factory tow package. Round trailer
plug at the hitch. The heavy duty signal relay and electric brake
controller plug and wires are in the glove box. The owners manual
says the brake controller wiring harness plug is taped up under the
dash on the left side of the steering column. I'm been looking all
morning and pulled the lower dash panel off to get a better look. I
can't seem to find it. Any other tips on what it is I'm looking for
exactly?

Considering the change to the 4-digit designations didn't occur until 1994,
I'd say that's pretty rare :)

Yeah - they really like to hide them sometimes. Under the dash, on the
firewall, will be a big (maybe 3"x4") plug, with about 100 wires coming from
it. Check around there, or even tucked behind it, for the blue 4-pin
connector. At other times, they tuck it behind the trim/padding next to the
emergency brake.

Sorry, I meant 1997.

Thanks. I'll take a harder look around and behind things.

Wow. I was going to reply -- after 28 years, the original wiring harness
still there?

Actually pretty unlikely that it would still be there on a 97.

I found it. Tucked way back inside a metal bracket. I found it with
my hands first.

Thanks again for the advice!
