HondaCB650

I have been racking my brain for the past 2 days trying to figure out how to wire an aftermarket Emgo right hand switch to replace the OEM unit ('82 CB650SC), any advice would be greatly appreciated. What I've come up with is:

OEM Wire to New Switch Wire:
Start Button - Blue/White to Blue - switched hot to dimmer
Start Button - Black/Red to Black - fused hot to start button
Start Button - Black to Red - switched hot to start button???
Start Button - Yellow/Red to Black/Red - start circuit to starter relay
Engine Stop - Black to White - switched hot to kill switch???
Engine Stop - Black/White to Black/White - ignition hot to coils
On-Off Switch - n/a to Yellow/Red - not needed?
On-Off Switch - n/a to Yellow - not needed?
On-Off Switch - n/a to Black/Yellow - not needed?

Plan to use the OEM connector.

Use a volt meter to make sure you have the right in and out for all the buttons.
Also make sure it grounds to bars if you have new bars or chrome bars you might have to grind a bit undernieth so it makes contact on the switch ground
