Re: 93 idi ip shorting out, glow plugs shorting as well
Well, what is the purpose of the wire to the insulated spade connector. Not sure where the fuel heater is, but if it ties into the pump, you will need an insulated connector on the line side of the pump. You really need a schematic. I found an electrical schematic for the 6.0L, it showed either 5 wire or 3 wire, depending on where the grounds combined.
Ever notice that there's so many high performance parts available for GM products?
Did you ever think that maybe they NEED them?
