Just I little int intimidated by the 02 controller wiring I guessI did one on mine years ago, mine was the MS2PNP version and it was as simple as unplugging the factory unit, installing the MS unit, running a vacuum line through the firewall, and maybe a ground/power wire IIRC. Maybe those wires were for the Innovate LC2, don't remember, but that was easy as well! Car fired right up with the base tune and it worked really well.
