I need the wiring diagram for the GM keyless entry and the door locks for an 04 H2. Pretty sure it ties into the BCM behing the headlight switch.

For those that dont know what this would do...it would unlock all doors on first press of unlock, and give you a second channel (press unlock twice) to turn on something else.

 

Pretty cool idea, not sure about the wiring diagram. I am sure someone might have some info on it.
I am not sure what else I would want to control with the second press of the remote. Aux/Spot Lights?, Windows? Air horn? Back Window on SUT? Interesting idea. This might end up being a pretty cool hack now that I think about it.

 

I did this on my 01 Ram Air Trans Am... I have red bulbs in the ram air scoops in the hood and side vents on the car that can be turned on/off w/ the second unlock press.

Your significant other will apprechiate it also...mine has been standing in the cold/snow/rain alot while im already in the truck wondering why the hell she hasn't gotten in.

 

That's a good one!!! Do you know "DIY" in Hummer parts like the door? I have a 4 door hard top. Is it possible to buy a waggon type back, hard top & where can I get the genuine parts? I also have slant top, could I convert this to a waggon type by cutting out the slant back? Thanks!!!
