Bit of an update. Got the input side wired up!! I ordered the m button to make wiring a little more simple, unfortunately, it never worked. Im not sure if it never worked from the get go, if it was getting interference or what, but I had to scrap all the wiring I did and basically start from scratch and wire the input side independently. That said after redoing all the wiring, I turned the bike on with the m lock, hit the buttons and they all registered at the m unit. Even got the motor to start cranking! Although I will need a new battery, naturally. I've been working about 50+ a week now, so progress is slow going but by God I'll have this bike out for a fall ride if it's the last thing I do. All that's left is the output side of the wiring and some tidying up of wires and fingers crossed my next post will be a video of my ugly mug starting it up.
