My 1999 Lumina has the standard guage cluster with no tach. I have a tach, but am unsure where the signal wire AT THE PCM is. If I can be informed to where it is, then that's be OK. Otherwise, can I just get another cluster from a salvage yard with a tach and use that? I see listings on www.car-part.com for 3100 with tach, or 3800 with tach, police package...what's a police package? Sounds cool.
But, really, what options do I have for alternative clusters? Or, where is the RPM signal wire at the PCM? Thanks.
