Ignition wiring help!

Okay. So I bought a 68 F100 with a 390 in it. Long story short, that 390 got toasted. So I bought my bro's old 78 F150 which I was told had a 390. Started pulling it, and it's a 1970ish 351W out of a Mustang. Bored .060 over, dished pistons, ported heads, and all that neat stuff, so I really wanna make this work. It's already dropped in and all I'm waiting on is the wiring.

It looks to be a duraspark ignition system of some kind, and I believe I have everything wired correctly, except the white and red/blue wires from the module. Not sure where the hell those go to, because my ignition switch isn't labeled. On the ignition switch from the donor truck, the white went to I1 and the red/blue went to ST. Does anyone have a diagram of the stock ignition switch for a 68 F100 so I can maybe figure out where these two wires go?

Ok, so I'm pretty sure I know where the white wire goes. It should go to the starter solenoid, if I'm reading these diagrams correctly. So the only mystery left is where the red/blue wire goes. I do have a red/blue wire coming from my ignition switch and it also goes to the starter solenoid, on the opposite side. Does it need to splice into that somewhere?

Here's the wire that's holding me up, btw.

This is the closest I seem to able to find at the moment...and I hope you can read them as I'm having computer issues with scanning

This is a 1970, but I'm pretty damn sure they are the same:

Ignore the pencil writing, was on them when I bought them

Wiring can be a real headache , and it is also like a
Math or calculus problem, or even a computer program
It just has to be a certain way or it isn't going to work at all
