So the meter receives two signals and interprets the differential as your speed, right? Then I would expect that the wire going from the meter to the ECM would be the one carrying the signal I need to send to my brake module. Probably the same for a power commander.

One signal.

But it takes both wires to complete a circuit to measure the signal.

I can touch 120 VAC and not feel it, if I am not grounded.

Put my meter on it, dcv setting, other lead grounded to a screw. Started bike on center stand and put it in first. No reading.

Thoughts?

Which screw?
What is resistance from that screw to battery negative post?
