Yesterday I was able to fully hook up a Yamaha MS-1 bike controller for PS2 to play my Model 2/3 motorcycle games using jumper cables crimped directly to the filter boards, so I can change polarity of pots to my liking, as well as the pinning for certain games.
You'll probably need a table clamp for this wheel as the suction cup system is rather poor, but this was a rather fun and simple mod; you open the main body of the wheel and there's the potentiometer for steering and some harnesses for the lights, but I cut those for my first attempt. Perhaps they would be cool to later wire up as the header lights in Harley LA Riders.
Previously I've opened up two other motorcycle controllers; the PS2 Thrustmaster Freestyler Bike and the Interact Xcellerator for N64, and they both require much more complex disassembly and the Interact one needs modification to pots. I ended up damaging the brake spring on the Thrustmaster one, so sadly I ended up tossing it.
To access all the buttons and pots you open up the big screw in the middle to pull the bar from the shaft, then you open up the face of the controller from the back with 5 screws. All the connections are labeled on the PCB, though the grounds for buttons are not labeled so I had to do a bit of guess work to ground those. For testing purposes I just plugged jumper wires of the buttons and grounds into the filter board and it gave a signal.
- These are the jumper wires I used:

- And I additionally soldered the jumper wires from the JST connectors inside the wheel to this data cable, as IMHO it makes a much cleaner outcome than having a bunch of wires dangling the floor. It's not the most snug cable I've used but it's just nicer to use data cables than use bare wires and zip tie them all the time.
