OK Changed the battery, pulled out the box, separated the FCM, blew it out with air and put it all back together. Now I don't have a drop with the power off, but I have no horn, no fog lights and the headlights come on when I turn to the parking lights. I guess it could be the TIPM, but I'd like to figure out what it really is. This is so aggravating...

still sounds like a mouse to me
i would check all your wires where you moved stuff around make sure nothing is damaged

i had a 70 c10 that acted kinda like this and it was all form mice

ok, wires are good. but... I found out last night while driving back 2 hours from the race track, I have no brake lights, no turn signals on the outside (it flashes inside the car), no wipers or fluid squirt adn the high beams won't stay on. Anybody know how to check the TIPM or the FCM to diagnose since everything I've read points to these?

Have you changed your trailer plug yet? Same thing was happening to mine, lights were always on. Ended up being the 7 pin plug itself was corroded.

Didn't try that yet. Talking with my friend who runs a shop, he thinks the FCM has died. We're going to try and check that this weekend depending on his schedule.
