When hooking up a tachometer where do you hook the green wire to?
The green wire should be the ignition(-). Do not confuse it with the regular ground. Check your manual where to find your diagnostic connector( the one they put a jumper on for smog check, and where the diagnostic codes are checked); it is usually in the engine compartment, or maybe under the steering wheel.It is usually covered by a cap that says DIAGNOSTIC. Somewhere in or around it there should be the IGN- hookup. Some other possibility would be to check for the ignition- cable coming out of the distributor(that is if you have a distributor). My 91 Toyota has both, but I hooked my tach to the IGN- right besides the diagnostic connector in the engine compartment. WARNING; my tachometer says that when the tachometer is hooked up, never let the tachometer ground itself( it means it should never touch the chassis or any metal, and also that the cables going to the tach should be VERY WELL SHIELDED!!); otherwise it would ruin the coil of your car. That also means be careful with the cable not getting frayed or where you place the screws if you hook the tach to the chassis.I would recommend hooking it to a plastic part of the console, or place it over a rug or rubber glove so that the tach does not touch ground(chassis).
