A couple of questions
I just pulled out the large hole GP's out of the 77 donor motor. On the receiving 80 body there is a box with a plug connection for the GP's that has a harness with a wire going to each one of the GP's. Once the new larger 80035's get here can I hook it up the way is was on the old 80 engine, that has the smaller hole GP's. Will this work and make the glow plug indicator light work on the dash?
#2 at the end of the series of wires should there be a ground wire from the last GP to a ground?
