To start the car, The gray wire in pin 5 of the keyswitch connector (which is the +12V via the AM2 fuse) has to get jumped to the Ignition and Ignition 2 wires and then to the starter wire.

Ok, that's straight forward enough. In order to keep the ACC (mostly A/C!) on I am assuming that the 12V needs to stay connected to the ignition 1 and 2 wires? Or is that what the ACC wire is for (is it even possible to start the car without accessory power on?) Thanks for your help!
