i had a transmission swap done, auto to manual and everything is fine except i cant get the speedometer/odometer/tripometer to work. the car didnt start with the manual computer in so i kept the automatics computer in but the harness is different. for the auto there is 3 wires and for the manual there is 2 wires for the speedometer. my mechanic ordered a senor but we are still trying to figure this one out. would anyone know how to get them working ?
