I can't recall anything about the starting signal.npez wrote:I think I have all of the wires worked out except for 2.
1. Has anyone used the cranking signal wire (it is the Black/Yellow wire in the M95 connector in the foot well) when hooking their wiring up? I don't see a destination on the Q45 harness.
2. The Yellow/Blue wire that the FSM on the Z calls neutral switch; is this the clutch interlock circuit (that's what it looks like)? It seems that when the switch is closed it goes to ground. On the Q there is a Park/Neutral Position relay with a Gray wire and a Blue wire. Do one of these wires need to be grounded to signify a Neutral or Park condition? I'm trying to determine the recipient wire to integrate the clutch interlock circuit with the Park/Neutral circuit and if that's the case it makes it easy.
If anyone has any insight to this, it would be greatly appreciated.
Thanks,Nick.
The interlock wire does not need to be connected to anything at all. I believe that if grounded it will not allow engine to start so hooking up to the clutch interlock is possible, however, even with the interlock wire disconnected the car will still not start with the clutch out. The clutch safety runs through the switch on the pedal before going to the start relay so it's already wired up to work fine with the vh ecu. Easiest to just leave the interlock alone.
The wire on the drivers fenderwell that's labeled neutral actually goes to the transmission to indicate neutral to the ecu to allow the IAC to keep the revs up in between shifts on the V6. Not sure if one can incorporate it into the vh ecu or not. It sounds cooler when the rpm's drop fast to me so I did away with that wire....and the iac too!
