Hello,

I need the pinouts, function, and wire colors for the 24 pin ecu
connector and the 14pin body connector that has the starter signal (big
spade), etc on it.

I dont have an electrical book here, just the crappy service manual.

I also have a mystery mk2 connector that I have no idea what it does.
Its right near the battery, 4 wires, 2 are pink (I forget the tracer
color), but it was badly corroded and one termincal broke off. We
think it's for some kind of headlight thing. Does this ring a bell?

"I dont have an electrical book here, just the crappy service manual."

What's on the website, is what I have, the factory service manual. I need more info than that. The info they give you is useless. I need info like "on connector X, pin 2, is the main relay in"

eh, thought I saw something that would help in the EFI section but nevermind. Your BEST bet would be to register to celicasupra.com forum and ask around there

The 14 pin connector depends on what year the vehicle is. So what year is your car?
