Just got my camera. Was looking to see what lenghts you guys used to run the video signal. I have an AVIC-D1 so it needs to go up into the dash. My truck is at the dealership so I can't measure it with the tape measure. I'm thinking somewhere between 12 and 18 feet. I have a supercab with 6.5' bed.

 

Depends on where you mount it, etc. I used a 25 foot run, because I had it in stock, and it has about 4 feet extra. That's from the rear bumper, passenger side, along the wire harness that is already there, up to the engine compartment, and through the rubber plug under the master cylinder.

I think mine is about 16 feet. It runs along the driver's side, through a grommet under the truck just in front of the left side of the driver's seat, under the sill plate, behind the emergency brake release, under the dash, to the stereo. I think I have about a foot or 2 extra.
