Fellow sparky. Just seems like a lotta brains going through that box, oh well, I'm committed at this point.Well I am a maintenance electrician so for me it wasn't bad at all. I take high voltage mechanical switchgear apart and put it back together with no spare parts.
I am not an auto mechanic by any means but I can install/take apart mostly anything and get it back together properly. There is a Genesis video of the install that is excellent.
