Hey, if it helps- good wiring is a reliability mod! Sure, it's not a shiny supercharger poking out the hood or a loud exhaust but chasing wonky electrical issues is not fun.Just sucked it up and bought the wire harness. JEGS finally ran a discount code $50 off $500, which essentially took care of the taxes.
That's an insane price for a wiring harness, but I suspect it will be a small price to trade for all the aggravation it will save me my first time wiring.
It will be a few weeks at least before I get started, but I'll update with my experience with the American Autowire harness.
