Once you take the panels off around the steering wheel which you need to do anyways for the install. You'll see a metal bracket near the steering wheel that has a bolt going thru it. I used that for my ground.silly question, but honestly, I am electronically impaired....where is everyone mounting the grounding wire for these redarc controllers? i just got my LC new last week and have a redarc TP Elite to install this weekend. Thanks!
