So i had purchased a shift light from this company their hand made. the guy i guess owns a Camaro, and has designed them to fit snugly(grammer) into the little circular vent on the driver side pillar.
the shift light only has a power ground and signal wire. (3 wires) it says in the directions to "Green Wire – This is the Tach input to the module. This can be either from the Tach line of the engine
computer or from the switched side of an ignition coil."
i had attached it to the wire going to my ignition coil (1994 mustang GT) and i set the shift light for 5800 RPMS and the light comes on when you hit 3000 RPMS with more then 3/4 throttle. so i figured not a good spot. and i tried to find the Tach wire from the ECU. (OBD1)
the signal just seems to erratic and inconstant from where i had it setup at.
where is the Tach wire on the ecu harness located a picture would be wonderful!!!
someone PLEASE HELP.
