OK, here's the latest:
I took the voltages at the engine side of the firewall of the 3 connectors. There were no wires running, so I was getting a good ground.
voltages are for the Top/Left/Right connector
Parking light on - 0/0/0
Left signal on - 0/12/12
Right signal on - var/0/var
var = varying voltage... so, blinking.
Per the diagram it should be Top (right signal), Left (left signal), Right (parking)
I think I'm going to have to dig into the parking light switch and do some wire tracing to the signal switch now.
