I need help to find the tach signal on an Alero 3400 1999 swamped into a cavalier, some people say to find the white wire that goes into the ignition control module, but I don't find this f***ing wire, I try different wire, but the rpm reading it always wrong, I used a scanner to get a good rpm reading. If someone have any suggestions ?
