How can I get a signal from a 1999 3800SC to my stock 1996 Sunfire Tachometer in the Instrument Panel ? I know it goes through the PCM into the I/P PCM, but where can I pull from the 3800SC and send it ? Crank Sensor w/ original Ignition Module ?
With most cars- you can use the wire on any fuel injector that is NOT common.
