Same thing with gauge cluster plugged in.

This is good! Shows there's no short on the harness.

Plugged green and black wires back in, plugged gauge cluster back in, took reading from black wire (at ecu plug) and chassis ground. reading 4.1

the only change here is you plugged spades back into coils? Gauges previously plugged in and ECU disconnected? If so, we may have shorted left coil. Try this:
- power off
- disconnect black & green spades from coils
- measure resistance between coil terminals of right coil
- measure resistance between coil terminals of left coil
- measure resistance between free terminal of right coil and chassis ground
- measure resistance between free terminal of left coil and chassis ground
