parking brake sensor? where is it?

yea...where is it. or better question. u c i got a screen but i cant watch movies unless i connect a wire in the back to a (-). it says that it has to be the parking brake sensor but i no i can trick it. any suggestions?

I don't think that there is a "parking brake sensor" persay but there is a parking brake warning switch and an ABS Sensor Block. the only reason they want you plug into that one is because it's a "safetly precaution" so that unless you have the parking brake on which toggles ground to complete it's circut then your screen won't work. You should be able to just use any good ground. I Have a list of factory grounds if you let me know where you are installing the screen i might be able to find the closest (-)

The parking brake sensor in near the e brake.

With that said you should be able to use any good ground to make it think the ebrake is set.
