Does anyone have a 2005 Tahoe wiring diagram for a remote start install? I searched all over, and found 2004's, but would like a 2005 just to be on the safe side.
Other #1
I have purchased a Peripheral doorlock interface w/ window roll up module. It does not indicate how this works, only that it will work for my truck. I would like to use this feature in place of the trunk release. Any ideas on how this would work?
Other #2
My alarm, a 2-way fm unit called a Nitro (dont laugh) has a harness for something called a Central Lock. I thinks its for door locking, but it also has the normal door trigger - and door trigger +. The wires are labeled as such -
Unlocking NC
Unlocking COM
Unlocking NO
Locking NC
Locking COM
Locking NO
NC=(Normal Close) Node
COM=(Common) Node
No-(Normal Open)Node
Is my thinking right on these wires??
Thanks for any help or suggestions!
Steve

THANKS!!! Any thoughts on the power window roll down options? The charts dont list any power window wires. Anyone ever get something like this to work (window down instead of trunk release)?
Thanks Again!
Steve
