Is There A Wiring Diagram For The Is2 Somewhere?

[RCAnderson]

There's a couple of things I've been wanting done differently with my IS250, firstly, I would like the wing mirrors to automatically fold when the car is locked (but I could like with when the ignition is turned off) and unfold again when unlocked. The second is for the doors to auto lock when travelling a set speed.

I know you can buy units that do this, but that got me thinking, would it be possible to make my own? For example, if I made a module powered by a micro processor, would it be possible to control these things myself?

The main thing stopping me giving it a go, is how any signals are communicated through the car. For example, how much is direct connections, and how much is done over a network. If all the signals I need are done with the former, it's quite doable, if it's the latter, it would me more complicated/not possible. Does anyone have the wiring diagram, or information themselves that could help me decide if this is doable or not?

you can access them here:

pay for an hour or two of access.

Ah, cheers for that. Looks like it'll probably have what I need, and isn't too expensive for temporary access :)
