A/C compressor relay wire colour

Post by **Bennoz** » Thu Jan 14, 2010 12:12 pm

According to this ECU pin out, the AC signal wire is connected to pin 22.

If anyone has their car in peices, can anyone tell me what colour the wire is?

lol, I love answering my own questions

FYI, the A/C trigger is a yellow wire with a green stripe. It goes into port 45 of the ECU.

Its ok mate, its not a question I expected anyone to know. Ended up getting the info from the Guru's in the UK, Eurospec.

I was able to find the AC relay wire ok, but didn't know what the trigger wire was (the one that's activated by the climate control unit when you hit the A/C button)

Now im just trying to find out whether it needs to go into a digital switched input on the Haltech or a digital pulsed input

I was just thinking I would not have been able to tell you what was what any way as I don't have climate control.
