anyone know where to take a tach signal from on our cars?
problem solved

well share the cure, it's what this forum is for
it's a secret...
well, it's pretty obvious actually and sort of specific to the software i'm using.
anyways, my split second unit will allow me to take the signal from any of my coil packs and will use a "divisor" or "multiplier" to turn that into the true rpm... or so they say. I'll know for sure tomorrow night.
This is assuming the 3 wires to the coil packs are power, ground, and the signal i need to do this (which sure makes sense to me)

it is also the green tach signal wire located behind the cluster
it also goes to the ecu/a/c unit and the alarm box locate on/behind the right side kick panel

is that how it is on your car?
i've been told there are changes in '99. Of course there HAS to be a tach signal going to the tach of some kind, lol. If i have trouble taking it from the coil pack i'll go looking for that wire color at the ecu (which is located where in my car...)
