Hey Guys,
Just wondering what some pins on the stock ECU actually do.
103 Battery backup power supply (constant 12V) - Is this just a constant +12v?
108 Ignition switch - ST - ?????
110 Ignition switch - 1G - ????? are these just +12v outputs when the key is in the ign position? What is 1G / ST?
62 Purge control solenoid valve - what is this?
56 MPI Control relay - what function?
66 MPI Control relay - what function?
65 Air conditioner relay - ??
13 Control relay (Fuel pump drive signal) - pull down to gnd?
5 Power steering oil pressure switch - what does this do in the stock car? increase revs once pressure was detected???
7 Air conditioner switch - ??
Just wondered if anybody has more details for these pinouts found in VFAQ before I pull out the multimetre and start testing. It may save me a bit of time instead of testing.
I'll be drawing out a diagram first so I'd like to match up the motec to the stock loom first with some temporary wiring and then make a final loom for the AMG galant.
Thanks guys.
