The electrical is not hard at all for the new gauge setup especially if the the oil is mechanical....

Your new gauge would be wired like this (if all electric)

1 wire from temp sender in motor for TEMP Gauge
1 wire from your GEN or ALT to the BATTERY Gauge
1 wire from oil psi sending unit to OIL Gauge (if its mechanical then run a 1/8" oil line to gauge)
1 wire from fuel sender should already be there. the send unit should be the same.

The gauges should have a 1 ground wire that loops to each of them or they may be on a common bus on the backs of all the gauges. ground should already be there.

So if anything you would have to run 3 wires into your engine compartment, 16 gauge size wire and color code them GM colors. Get the wire at NAPA. EASY!
