We want to leave the coils and swap just the output-wire. We are testing the hi-ten plug wire to spark-plug. If you swapped left output wire along with coil to right side and it sparked there, then that should be good enough to rule out spark wire.

Yep.
1. Here's solenoid test-light. It has duration-extending circuitry so that light stays on long enough for human eye to see. Otherwise flashes are too quick. Connect to each side of ignition-coil and should show flashing.
Solenoid test light
2. If coil not getting grounding signal from ECU, test continuity of black-wire from ECU to coil. Should be zero-resistance end-to-end on each side.
3. Connect solenoid test-light directly to ECU's output to coils. Use +12v power to ECU for one side. Should have flashing at ECU outputs on each side. Otherwise ECU's bad.
