I had luckily kept the old harness and panel to check items like this, thanks for the help tho......
On an OEM motor the wiper switch IS the ground. The yellow is power, the motor grounds THRU the switch. - https://67-72chevytrucks.com/vboard/...d.php?t=695112
When the wiper switch is turned on, it completes the circuit to ground (the dash). - http://67-72chevytrucks.com/vboard/s...d.php?t=413551
