Getting my fog lights to behaving similar to DRLs

Getting my fog lights to behaving similar to DRLs I still want my fog lights to be controlled by the OEM switch, but I don't want the power coming from the parking lights.
My plan is to use one of the output wires (dk / lt blue) from a DRL module as the input to the fog light switch, which of course leads to the fog light relay. I've already purchased some spare DRL modules, (Why not? It was $5 for three at a junk yard...), but I was hoping someone knew what each wire's job is so I can figure out what to splice. It would be silly if they blink with the turn signal or hazards, or get disabled when the head lights are on!
On the black connector, I understand what cavities E, G, B, and C do... turn signal inputs (left & right), and turn signal+DRL outputs (left and right), respectively. But what about the other cavities? Cavity A has 18 ga. orange, D has 12 ga. red, F has 12 ga. yellow, and H has 18 ga. brown.
What about the blue connector cavities? A = black; B = <empty>; C= pink; D= tan/white; E= lt blue; F= brown; G= yellow/black; H= green/black; I'm assuming ground, ignition, ?, ?, parking lights, high beams, and low beams, respectively. Which one is trunk release disable? parking brake disable?

Why go to all that trouble? You can just connect the fog light switch power (brown wire) to an ignition switched source such as the IGN port in the fuse panel and the fog light relay power (also brown wire) to a fused constant (battery) source at the junction box under the hood. That way the fog lights will be on as long as the ignition is on but you can still turn them off with the switch.

I did this today. I hated having to turn on the parking lights to get the fog lights to work. I hooked the brown power supply wire on the fog light switch to an ignition switched wire in the dash fuse box. And on the underhood fuse box, tapped power for the fog light relay from the 20A horn circuit.
Works great, and no chance of leaving the lights on because they turn off when the key is out.
