After trying two other methods for disabling ABS on my 2020 Wee, I spliced the switch into the red/blue wire coming out of the connector near the seat. This method starts out like "ABS defeat switch installation", but instead of removing the battery and all the work of disconnecting the ABS connector, it just splices the same wire near the seat, as outlined in "2019 Dl650 ABS switch". I used 14 AWG, waterproof butt splices (heh, heh, he said "butt") and wrapped it with split loom wire conduit to guard against chafing and/or shorting 25A wires. The hardest part is routing it without lifting the tank.
So after two false starts with the previous methods (resulting in a lot of frustration), I will say that this method works on a US 2020 Wee. While riding with the switch in the "on" position, ABS functions normally (kind of important). When switched off (on the fly - you don't need to stop or anything) the ABS light goes on, you lose ABS (as expected) and the speedometer, traction control and everything else works. Switch ABS back on again and the ABS light instantly goes out and ABS works again. No restarts necessary, no FI codes, etc.
My thanks to Rolex for the nudge I needed to try one more thing by reminding me that I could test this method before further hacking up my OEM wiring by just pulling the fuse with the engine running.
