2006 base Vibe Compustar 900-as install. Ive tried using the pin27 black wire off the pcm but im not getting the signal that I expect from that wire. It doesn’t go low. It changes very little with rpm and is around 8-10volts. I’ve tested all the wires in the right plug on the pcm and also the wires at the cluster and none run 0 volts at idle and increase with rpm.
Any suggestions? I’m using tachless mode but it’s spinning the starter way to long.
