i think i'm the only other one to do it like mike so far.
i followed his directions partially. once you have everything its really not that hard to figure out what needs to be done.
i bought ALL electric gauges. my electric speedo had to have an autometer sending unit. that unit has a place to hook up a cruise control cable, but mine is an '86. not sure what differences there would be with your efi. and i removed ALL of my cruise control equipment.
