Wiring is pretty simple.
Run the skinny green wire from the M-Button to the 'Config' termianal.
Outlets leads go the places they are labeled for (L turn, horn, etc).
Connect the tail light and brake light hot leads together.
When you set up the giz, choose 'single tail/brake light'.
Run the rear brake light switch wire to the left side of the M (input side)

Mine is the early one with 1 Aux circuit, so I had to make some compromises. I ditched the decompression solenoid circuit. I'll just reach over and hold the lever down when I first hit the starter switch.

Here's a tighter shot of mine. I used a start relay like the one you are looking at. In it is a main fuse.
Battery + goes to start relay.
Fused + goes to the indictated + on the MotoGadget.
Key switch picks up + from same place.
Key then sends signal to other side of gadget.
Only oddness is that the rear brake light switch goes into the brake switch input, because I didn't want to run it into the headlight bucket to the MotoGadget M Button.
I only have the ignition on the 'Aux'. Didn't want some minor electrical problem to knock out the ignition. So, you have to get creative with the lighting. Later systems have 2 Aux circuits, so you can run ignition on one, lights, etc, on the other.
Power from R/R goes into a 'Y' connector with hot from start solenoid. This way, the Gadget is fed from either the battery or the R/R or both.
Ignitor and coil get their juice from the Aux.
Did the combo brake/tail wiring option.
Am I making sense?

i got the M-unit blue, so 2 aux.

actually it got me more confused

found these two on Revival Cycles:

https://technicalarticles.revivalcycles.com/hc/en-us/articles/360009106131-m-Uni
t-Blue-Basic-Universal-Wiring-Diagram

https://technicalarticles.revivalcycles.com/hc/en-us/articles/360016301611-How-t
o-Integrate-a-CDI-Ignition-with-an-m-Unit

from what i understand there are a couple differences between your way and their diagram.

any pros/cons between your way and the revival diagram?

sorry if my english is bad, Norwegian first time builder with no clue Tongue

This is all great stuff - I'm just about to begin wiring up my m-Unit/m-button/switches, and I understand about 90% of what I need to do. The spot that's vexing me a bit is which bits of the ignition system do I keep from stock, and which bits are replaced by the m-Unit? I've looked at the two revival diagrams, and that clears up a lot, but any extra advice would be welcomed.

Hey ghyrx
On mine, I kept the original ignition-coil, crank trigger, and ignition box. I ditched the starter decompression thingie. Wiring between the crank trigger and ignition box is stock. Wiring between box and coil is stock.
I have the early M-Unit with only one Aux outlet. I ran that to the hot side of the coil and ignition box.
Key switch controls the main juice.
On mine, start and kill are the same button. Momentary for start, hold for kill.
Tail and brake are the same wire.

One other question - with the m.button, the front brake switch is handled via the single green wire to the 'kill' terminal on the m.unit. For the back brake switch, though, will it work to simply run to the 'brake' terminal on the input side of the m.unit? I can't find if there's any weirdness when you use the m.button but still need to use other inputs. My gut says it should work no problem, but can't hurt to check, right? Wink
