How to hot wire the Yaris

If you look at my DIY wiring guide for remote start, everything you need is there. You basically would have to jump yellow to pink, white and green to run and yellow to black momentarily to start.

Not really interesting in hotwiring so much as DIY remote start. Except I don't plan on buying a module, I'm going to build it from scratch and use my EZ430 Chronos RF wrist watch to send packets to the radio which will start the car and lock / unlock the doors and activate an APRS beacon (all sorts of fun!).

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)
