I posted its an 85 300sd 617 motor. I had all the wires unhooked even at the junction box but Im pretty sure I got them all back in the right spot. Car turns over good. Everytime I plug the glow plug harness in there is no juice to plugs I have to wiggle the plug that has the 4 wires in it I thinkit goes to the junction box on passenger side fenderwell I hear a click and I have power coming off the 5 prongs out of g.p. box but the minute I plug the g.p.'s in no power to the plugs kind of like something trips then when I wiggle the 4 wire small plug seems like it resets.
