F1A4 DD/Mono toggle DIY(help)

[downhalo]

Hey all, So i've been thinking about adding a toggle between DD/Mono for a couple of F1A4 units i have..

I'm not quite sure how to finish the job.. I've thought out most of it, but don't know where to go from here.. (below image says it all)

Logic says I'd need to re-wire the chassis and connect it all via a 6 pin toggle.. on-on DD-mono..

Anyway If you're able to shed some light on the subject, I'd much appreciate it..
