99-05 PCM Circuit 1020
Can someone tell me what circuit 1020 does in the PCM? Its located in the blue connector (C1) Pin 75. Cars (LS1) don't use it but the trucks do. I realize its an ignition hot, but just wondering why the cars use it and trucks don't.
Thanks in advance.
I'm looking thru 2001/2002 F-car schematics and I don't see circuit 1020... I'll tear my hair out.
looks like switched 12v to me but I don't know why. Pink wire....

FWIW - I have seen this circuit labeled as "PCM Ignition Supply - Off/Run/Crank Voltage" and "Ign 0 fuse - Acc/Run/Start Voltage". Not sure if it's doing something special or not, but those are some of the descriptions I have seen in the truck / van schematics.
I looked in the 2001 F-car connector diagram, C1:75 is listed as not used.
joecar,
Correct, it's not used in the Camaros. It appears to only be used in the trucks / vans.
Wonder if its for remote start features?
