,
This is my first installation on Hummer.
One guy come to me with its own Chinese GPS/GSM remote start alarm system and asks me to install it.
Can somebody help me with some connection points. Especially to lock/unlock doors on H2 2009.
Actually I connected lock/unlock from the driver's door module, but when I'm starting and shutting down engine, the instrumental panel stays with lights on until any of doors will be opened. The headlight switch is on auto mode always and goes off after about 1 minute.
If you lock the door with its own remote the panel light goes off.
So, where can I find and connect to the door lock/unlock wires, which turns off all lights.
Thanks in advance.

Will try by myself...
But if you have the experience, your help is welcome...
Thanks again anyway.
