Hello, I am installing a Jensen VM9021TS into a 2005 Nissan Frontier. I'm ok with the wiring, got the harness, with the exception that I'd like to properly connect the Head Unit to the parking brake. Does anyone have any tips on where the best place is to access the parking brake wire? The truck has the center console lever parking brake. Is there a standard color for this wire (grey/red etc.)? Any suggestions will be appreciated. I tried a couple of posts at the Nissan Forum and got nothing. Cheers,
