Does anyone have a "actual walkthrough" of how to install a A/F guage and a water temp guage? I want to install both and Im an electrical retard People always say go theough the PCM, I aint touchin that thing with a 10 foot pole, soon as I see all those colored wires in that thing I would have a heart attack. I need something like pretty pictures to help me do it, instead of a technical electrical wire layout of of my car. So for any of you who have done it or who know a site that explains it I would appreciate it a lot, thanks
