83 F250 6.9 IDI controller pin out diagram and wiring.
Hello new to this forum. My son has a 83 F250 6.9 IDI diesel. Someone made a mess of the wiring so we are trying to rewire the glow plug controller system including the pin out for the controller and what sensors on which pins. Does anyone have this what seems to be rear schematic or even happen to have a manual of wiring diagrams for it. We are trying to fix this old truck up and bring it back to original condition but having trouble finding specs and diagrams etc. Anyone happen to have the original mechanic manual for the truck? Or where we can find one. Apparently there are several differences between later versions after 83 so not sure what all applies from later models. thanks for you assistance in advance. warren
