I know I've read this before, but now I can't seem to find it. I'm removing the aftermarket stereo from my 92 Cab and installing the CR1. I have a mystery brown/blue wire that has a connecter on the end of it, but seems to go to nothing. There is also a brown wire behind the clock also with a connecter on it, but is just hanging out there. Ground them, don't worry about them? Thanks for your help!
