There is an orange wire, which is disconnected from the harness. The wire to 12v on the power supply is also orange. When I'm in diode mode (I looked it up), and I touch the multmeter leads to 12v on the power supply, and pin one on the harness, I get a quick readout (last time it was like 1400).
Should I attach the disconnected orange wire to the ground on the harness, and just see what happens?
