ya I am trying to work my way through the 89 harness.. I have had no luck finding a schematic for any of it except a pin-out for the back of the gauge cluster so if nothing else I will bust out the trusty voltmeter and start running continuity checks between the gauges and the plugs for the ecu so then I can get the gauges up and running.... thats about all I have left to get figured out and I can start soldering wired together...
