Nope, but now I truly understand what is breaking, but not how to fix it.
When I measure voltage at the body side connector with everything unplugged past it to the wheel I get 12volts on brown - good


Picture doesn't show it, but If I measure with wires connected together (entire harness assembled) I get 2 volts instead of 12 and no speed reading. - Bad
If I cut the wires and remove the wheel side connector and connect from body side connector to bare wires on the WSS via jumpers. I am back to 12 volts and get an accurate wheel speed reading.- good but unusable.

It doesn't matter if the WSS is mounted to the car or not. I always get 2 volts when the WSS connector is attached.

What am I missing that would drop the voltage just because a connector is attached (not even plugged in) the top picture is the connector I am talking about. Cut it off and everything works via jumpers.
I have tested 2 sensors. 1 brand new and same thing happens.
