Usually if you want to view dvd or other video source while driving you needed to put parking brake wire to ground. SNO
I'm installing an Infil G4 in a car primarily to have an in car tuning computer. I was tired of hauling around my laptop everywhere with me so I bought a G4 used to install it in my car.
Pretty much everything wired into the cars harness except the parking brake signal wire for the infil. I need to know if the parking brake signal is a ground signal or a positive 12v signal because the car I'm installing this into does not have a parking brake sensor. My thoughts are to just wire it up to constant ground or constant 12v positive since the car doesn't have this provision.
Please let me know.
Probably saved me from blowing something in my unit. I had it wired to 12v +.
yea just tag it into the ground wire and it should be fine unlesss u wanna put a switch on it like some of the pioneer radios needed
