Need some wiring help!
I bought a new head unit to replace my radio. Its a non bose, non navigation, base model corvette that I just bought a pioneer headunit fro crutchfield. The wiring harness came already put together with the headunit , although, there are two wires in don't know where they get wired in the car. the first one is marked as parking brake and the second is marked as reverse. I'm assuming the parking brake one goes to the light blue wire that goes into the parking brake? and I have no idea where the other goes. any help is much appreciated!!! I have looked at other posting, but they all don't seem to have this problem.

If the head unit is dvd capable, the parking brake circuit is so it will not play while the vehicle is in motion (the parking brake must be applied to provide a ground) Grounding this lead will allow video play anytime. (In most cases it is illegal for the driver to be able to see video while in motion)
The reverse wire when tied into the reverse circuit will switch the screen to the camera input.

I bought one along with this unit. the issue is more of the location I think. the reverse wire is pigtailed up by the head unit. My guess is the intent was to tie it in somewhere along the wire run of the car from the passenger side junction, however, I don't know if that will work and/or which one to even tie into.

The camera should have come with a 'twin wire cable' (for lack of a better description). One of the wires should have a connector on it that plugs into the head unit (the other end runs to/from the camera). The other one should have two bare ends; one end ties into your reverse light wire at the rear, the other ties into the wire on the harness marked 'reverse'.
