I understand how to wire it thru the pcm (read install university), however, they installed the shiftlite in the dash, so I'm not sure if I can use the same accessory/ignition/ground wires.
For those that have an aftermarket tach, how did you wire them? Do you have wires poking thru the dash? I'm looking for as clean looking install as possible.
