In your guide you do not talk about which wires actually carry what information (voltages etc). Can you list more specifics? Is there a single 12V line that gets jumpered to the various other wires which then trigger relays? If so, then this hotwire procedure has me baffled.

Thanks and this is going to be a fun project, just added cruise control to my '07 liftback last month and I've only had it for a month and a half. Also, I do NOT have an immobilizer so no big deal there. I DO have a manual transmission but that's easy enough to also jumper the clutch switch while remote starting (I don't really want to just bypass it out like others are suggesting)

Sounds like a fun project. I have been seriously fighting the urge to buy one of those TI watches, as I already have too many projects in the works.

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.
