Hi guys, I have a 1991 safari (jap import) just swapped the td42 motor out for another td42 out of a 1990, with a turbo ect. But now my rev gauge is not working. The sensor on the original engine is plumed in under the fuel pump gear. The engine I’ve put it plumbs in right of the water pump like most of them do... the wires and plugs are the same but the sensors are different... I know it was working before I pulled the engine out the other truck. Anyone had this issue before and how do I fix it??
