What to do with drain wire
I'm connecting up the factory spoiler camera. I have a lock pick so Id like to use stranded/shielded 18/4 from the camera, positive/ground to the lock pick, video positive/neg to an RCA pigtail, and that just leaves the drain wire. Can I just ground it? And to what? Same as RCA ground? Chassis? I've never dealt with a drain wire before, I know it normally connects to the sjb but I'd like to avoid getting into the factory harness if at all possible. Thanks!
