@Vernon Barry posted:Remember, certain powerhouse units had a microswitch inside the plug to turn them on. If you chopped off the end and didn't account for this, or if you used a plug socket (example harness used with the TPCs) that 3rd pin is required to turn on the powerhouse.
It would seem to me that this safety switch is internal to the molex plug. Once the molex plug is cut off I suspect the wires have voltage.
