THIS IS A DIFFERENT EXPERT.
You said " I had tested for current (and I did use a test lamp) and there was constant current at the bottom right terminal only, when the vehicle is running, but never any current at any of the other terminals"
Based on this answer to the other expert's questions, you have just found your problem. As he told you earlier, THERE NEEDS TO BE TWO WIRES live in the connector feeding the combination flasher/DRL Module.
You referred to the BOTTOM RIGHT terminal as being live. Good. That's the feed from the A22 circuit. There also needs to be a feed on the L9 circuit at PIN 1. This enters the junction block on pin 27, connector 2.

You also said " Doesn't the power come in on perhaps the red wire, then run through the multi-function switch to the Light Blue/White wire or the Light Blue/Yellow wire, if the turn signal wand is pushed? In which case wouldn't I need to jumper a wire between the red wire(if I'm correct) and the Light Blue/White wire or the Light Blue/Yellow wire, to have a turn signal turn on? I didn't want to short anything out, so I didn't test this idea.
This would be a good fast way to burn up your multifunction switch. The multifunction switch does not have current going through it for the lights on this model. It is simply a voltage signal circuit that allows the module to determine what lights to turn on. A small voltage is sent from the module to the switch and the switch pulls that voltage to ground on each terminal depending which contact is closed in it.
Please recheck and locate the cause for no power to pin 1. Please let me know if you require further assistance.
