CUCV M1009 Glow Plug Module Wiring

[jawalter]

I'm about to rewire my manual glow plug circuit. The person who did the previous job didn't know what they were doing. Here is my question - How many 12V feed wires (pink with black stripe) go to the connector on your module? It looks like there should be 2 wires going to the same pin according to the schematic on Figure F-7 in manual TM 9-2320-289-20. However, my glow plug module only has 1 pink with black stripe wire going to it. I'm guessing that this 2 individual pink with black stripe wire connection, that is shown on the schematic as being at the glow plug module pin, is actually made somewhere else in the engine compartment.
