I am waiting for my msd programable shift light in the mail and was wondering where is the best place to get a tach signal? Is there a good tach wire on the back of the gauge cluster?
for my raptor shift light install. it's recommended to use a signal from a coil.
didn't want to see any wires so. i followed the instructions by raptor. taping into a coil signal. from passenger side kick panel CPU, go www.raptorperformance.com/
had mine wired this way. 3years now very accurate, very easy.
