It's a personal preference ... chassis grounds are worse when it comes to loop issues but I have had issues with braces like this too, I believe in the Avalanche. You are correct though, they are LESS of an issue but can still be :P

I would like the wiring schematics for the under dash wiring on the H2. I'm looking at adding some things myself and it would come in handy knowing what I can/can't use ...

 

hmm....don't have the exact scematics...wow thats bad spelling right der...but I have the color codes for alarm/remote starter and anything audio/video you need.

 

I have 2008 H3 - colors still the same - wht/red=acc (off when key off)

Does any one know what the two 12 (+) yellow wires in the connector going to the 4WD/4WD HI/ LOW /Traction offDISPLAY are for.
Are these (+) for a switch or just to back light the display buttons?? They act as ACC WIRES.

THanks
