Does anyone know which wire brings power to the PCM? I am using a battery disconnect as an anti theft measure and when I turn the battery back on in the morning the PCM has to keep re learning how to idle my nasty aftermarket cam and its a pain in the a$$. At least I think this is whats happening so I want to run the PCM power wire to the hot side of my battery disconnect so it always has power. Any suggestions or info is much appreciated.

Thanks!

you'd be better off just wiring in a toggle switch to turn the fuel pump relay on /off ... maybe a toggle switch inside the glove box or something...

That way you have your stock (or aftermarket) alarm system armed , car doesn't have to relearn idle, and it's a theft deterrant as well...

Does anybody have a wiring diagram with the PCM mapped in it??

Looks like pin 20 on the blue connector should go to the battery. It's an orange wire close the the middle of the connector.

Awesome, thanks so much. Did you read the whole post? does this make sense or am I always going to have an idle problem until the o2's heat up? should I have my VE tables edited?
