by the way I know its ecotec
got you to click on it tho. so you might as well help me
I have the autometer tach adapter
red wire and the green/red are going to the pink coil wire
black to ground
grey to tach
tach hook up
red and the white are to the red power wire on my stereo
black to the stereo black
and the green to the gray wire in the tach adapter
I got full power to the tach. when I turn the keys on the needle goes to 500 and drops to 0
dose anyone know if the signal wire is a positive or a negative off the adapter?
rewired the wires to its own 12v power source so its not the radio fixed the sub on the up side tho
off the autometer 9117 tach adapter I have my red wire and the red and green wire going to the pink wire on the coil pack and im also getting 13 volts off of it tested it yesterday
do you know how to tell if a tach is defective?
you didn't give any more info. you're suposed to:
cut the pink wire
hook the red off the adapter to the side of the wire from the pcm
the red and green gets hooked to the side going to the icm.
by what you're describing, you just put the red and red/green wires on the pink wire. the tach adapter is meant to intercept the signal of the pink wire. if you just splice it all together, it won't work.
the red wire from the coild is your pink wire. the red/white is your red, the green is your red/green.

that's exactly what I did. the diagram said it needed a 12 volt source and the pink when I tested it was 12v so I took the easy way out and tried to get my signal and power supply off of it. stupid installer error thanks for the clarification
I looked back at my instructions and is dose say both wires off the coil pack
damn you autometer. but your right it needs a different power source. thanks for the clarification works 100% now
