[GrandSportTurbo]

Hello All,

I was just wondering if anyone could provide me with any ideas as to why my tach is not working. Please let me know the what/where/how so I can get it working again. My car has a 90 wire harness, using a 91 ecu, a 90 ignition module and a 91 coil pack. I modified the 90 harness to work with my setup, but the tach is being a little slut.

Thanks in advance,

my tach died when i turned on the lights, heater, 4 ways, cruise, etc..... all at the same time to try to get my idle down (lol) i blew like 3 fuses, so try checking all of your fuses (by the clutch pedal)

come to think of it, the whole left side of the instrument cluster died

wait a second, you modified the wiring harness?
disregard what i said
