Thanks, RalphP Update its pin 3 at Zero volts I'm getting confused because there is a major electrical problem! I can't believe the truck runs so good and drives awesome! The buzzer doesn't work, the horn isn't working, the cab lights aren't working, and the ABS isn't working. I just tested fuse 11 and its fine because I know it would be because the turn singles work so maybe if I wire 12 volts into pin three the ABS would come on?

 

Well, there's fuse 7 after the tap for the turn signals; did you check Fuse 7? That's for ABS/Buzzer/Brake Lights.

And how are you testing? Do you check across it with the resistance setting of a meter with it out, or through the top if they're ATO fuses?

Also, connector 3 will only have 12V when the ignition is RUN or in ACC position; check the switch, you may have a bad ignition switch. And you're checking the black wire, right? To verify you're not peeking at pin 8 or so.

I pulled open the 1994 FSM I have, and the wiring isn't what you have there ...

I've attached both the 4WAL and RWAL wiring schemes. Might want to use those to check with.

Brake pedal should be firm, with only a few inches of travel before things start happening. If it feels spongy, or squishy, there is something wrong, and you need to address that. (and may be why your abs lite stays on.)

 

Okay just to finish this thread up, the ABS works! The problem is the black wire that runs to it when the truck is running is broke or cut somewhere under the dash. I am going to try and find it and fix it but if I cant I will just run a new wire to the ABS. If you look at my picture I soldered that green wire on to fuse 11 and ran it to pin 3 on the ABS pcb. Then I started the truck and ABS and brake light came on for a second and then turned off! Another problem solved! Thanks, guys for helping!
