Tach wiring help
I've looked at forum after forum, and I don't know what I'm doing wrong. I have a 97 camaro z28. I'm trying to install a 5" tach. I have power, light comes on with headlights, and a good ground. But no matter where I hook the tach wire to it refuses to work. I tried the white ICM wire and the white wire in the PCM at A13. I've been stumped for days now. Any help will be greatly appreciated.

Sorry, didn't think of that. It's a 5" Autometer tach with shift light. Got it from a friend that had a v6 so the brown wire was cut but I soldered it together. Anyone use the crankshaft position sensor wire?

Re: Tach wiring help
The AutoMeter 5" tachs are calibrated for 4 pulses per crank rev. The reluctor in the 96/97 has 4 pulses per crank rev.
Note that different models of the 5" tach can be recalibrated via different methods. No substitute for the manufacturer's install instructions......

Typically, you put the green wire on the coil negative. This is not recommended if you are using a multiple discharge ignition like MSD, Crane, etc. See instructions.
