Well i went to the junkyard this weekend, got 2 auto down modules from 2 different ssei'*. Tried to hook them up, but no matter how i did it i couldn't get it to work. The colors on the modules are brown, grey, blue, and brown. No tracers. Can anyone further help my in diagnosing this? I can either get the window to go up and not down, down and not up, or nothing. I have an '87. The drivers wire colors are blue, and i think blue with a brown tracer. I still might want to attempt this so any help is appreciated.

Every wires on the module must be connected.

So according to you, the A (brown on my modules) goes to the PINK on the switch, then B (blue on the module) goes to the blue from my switch, then D (brown) goes to that same blue i just cut, and the C (grey) goes inline of my blue/white on the switch to the motor. I'll have to try that.

OK well i got closer. I followed the diagram, and i got it to do the auto down feature. Cool huh? OOPS just a second. Now there'* no up. I can only get it to go up if i directly connect BOTH the factory wires together, i can't have the module in between. If the factory wires aren't connected i can't use the up function at all. Any ideas?

You know... The colors aren't right in the drawing since I'm colorblind... And what year did you get the module from?

Don't worry i didn't use the colors i used the pin letters. I'm not sure the year i forgot to look, i got 2 different modules from 2 different cars, but both of them have the same wire colors. Brown, grey, blue, and another brown. Pins A, B, C, and D in that order.

Does one of the browns have a tracer stripe?

You are tapping into one wire and cutting the other of the motor power wires right?

Nope there are no tracers on any of the module wires. Yes i cut one wire and spliced into the other. No matter what way i connect it if both of the factory wires aren't connected directly, the way they were originally, i can't get it to respond to the up switch. Only the down, which does work auto.

Um... try more configurations.
