Trying to install my navigation unit and it needs to be connected to the emergency brake, can somebody point me to where this is at?

 

I didn't hook my head unit up to the emergency brake, and I wouldn't recommend it. If you are on a long driving trip, and you have passengers, they won't be able to watch a movie. You won't be able to do a lot of things while your driving because of it. I would recommend hooking your emergency brake sensor on the head unit directly to ground. It won't hurt anything, and you can still play a movie while in motion, just please don't watch a movie while driving.

 

I already have that bypassed, but I still need to find the parking brake ground I believe. Im installing a Pioneer AVIC-X910BT.

 

It will be one of the wires going into the plug that is on top of the pedal you press to set your parking brake. I'm not sure on the colors though for the '03 trucks.
