HELP! PCM Tach Wire Voltage I've wired up a window switch and an aftermarket tach in my 2002 Z28. Neither seem to be working. I double checked the wiring and I've confirmed that I've plugged into the pin 10 white wire on the red connector.
When I check the wiring with a voltage meter, I get about .009 to .03 volts at idle with no change when I rev it. That doesn't seem right.
Can anyone verify what voltage I should be seeing at idle?
