Hi, I am looking for a wiring diagram for a 420D cat backhoe, for my father. Can anyone help us out? He has written on this paper electronic fuel pump relay wiring, guess thats what i am looking for. Thanks
If you have a no start problem, look for a plugin diode in the harness half way up the LH side of the engine block. If it's shorted and has continuity both ways change it and try it. Later Bob
