Where is the ground at the back of the passenger's head? (on an LS1)
Therefore I was planning on grounding it at the back of the passenger's head (this is where the PCM, among other electricals is grounded), but where exactly is that ground? Accessibility there is nightmarish, I've felt the area with my hand and I didn't feel any bolt... so it's probably too far for me to reach. Where is it? If it's so hard to access, how can you possibly attach anything to it? Please help...
