The Bk/R wire should run from fuse 2 (10A) all the way to the front switch - no junctions. I imagine this is the wire the M-Max is (was) using for its power.
Best thing to do, I would say, is remove the M-Max (we don't like them here!!) and trace the Bk/R wire from beginning to end. Make sure it is a continuous wire from the switches' plug to the fusebox - rejoin/solder it as necessary.
Next, simply perform the wire-spice as per the MC21. The derestriction is outlined at the beginning of the ignition page in the 250 Tuning Section, and more detailed instructions can be found at the end of the page. If you do that, it elimiates one more thing from the mess that could be badly hacked up wiring.
We can help you obtain all the parts you need. Where are you located?
