I have a 97 transam and did an ls1 conversion. I have an msd tach driver and an autogauge tach. I need help wiring it and could you show pictures of your setup. I read the msd instructions but still doesn't work?

Isnt the Autogauge made by Autometer? If so, the tach should work by hooking it to the pcm output(C2 pin 10). You can set the tach for a 4 cylinder signal or program the pcm to output a 8 cylinder signal. You shouldn't need a tach driver.
