I'm installing a remote start system in my car, but I can't find the tach wire. Does anyone know what harness it is located in, and what color the cable is? I've looked over the diagrams, but I can't seem to find the cable that runs to the tach guage.
Tachometer blue wire AC under the distributor or side
You can use a wire from a fuel injector. They should have two wires. Look at all of them and use a wire that is NOT common to other injector wires.
