I'm hoping to have my motor in and the fab work done by this weekend. I want to make sure I wire the new motor the best way I can utilizing the existing 6.2 harness. I'm trying to use the factory chevy gauges and connect them to the motor where needed. Does anyone have a diagram for a OBS 1991 chevy engine compartment with the 6.2 diesel in it or now where I can get one? Any recommendations on the best way to wire the motor. It's a 1993 5.9 and I have all of the factory dodge harness and I'd like to use the intake heater and I have the relays. Is there any way to use the glow plug wire to heat the intake heater so I don't have to push a secondary button to heat the grid? Thanks for the help.
