Hi ya'll have helped me out before i have an 03 8g galant with a 4g64 engine. my speedodamer (sorry if i misspelled) when it went out i touched two wires together from the radio. there are no cpu lights. ive bought a speed sensor, instrument cluster, and the factory speed limiter still works because at 4000 rpms in 4th gear is stops me from going faster. Anyone have any thoughts. an employee of mine sad to check the ground wires from the instrument cluster to the ecu. but i can't find a wiring diagram for the car.
