Pinouts For The Ecu

[fmlycar]

What is this part got to do with the ac system. The motor that switches the vents works fine

Duncan, I back probed the pins on the ecu and pin 14 switches ground and pin 21 powers up with ac turned on. So I'm figuring it's just a simple rewire at the relay for the ac to get it all running?

Hi mate, sorry it was years ago I looked at this so I can't confirm. But I remember the issue being a positive signal from the ECU instead of negative, or vice versa.

I did run across a post on the Haltech forum the other day where another stagea owner had the same problem, so that is at least 3 of us now

I agree, it seems that checking the relay wiring would be the way to go. Sorry I don't have any specific input

Yeah ok. Thanks. I'm slowly piecing it together I think
