Hey guys, just curious if anyone has/knows how to install the wiring for rear defrost for our trucks. I have a tinted rear defrost window I just got installed the other day and the temperature controls out of a truck with a rear defrost button. My truck is a 2002 rcsb with a 4.8. I hope someone can help. I really don't want to go chasing wiring in my buddies exsb but that's looking like what I have to do. I did a search and found nothing. Please help!
