I've also come to realize all of the 3rd party Playstation wheels are very hard to mod because the buttons are not isolated and instead all on one motherboard, running directly to a black blob chip, so you will need to cut traces with a box cutter or an exacto knife. So they are absolutely not for beginners. First-party wheels or non-generic ones like HKT-7400 are nice because usually those have isolated pads and often have the circuitry in the motherboard accessible from the main body.
The one wheel I have been dying to use for my driving PCBs is the NASCAR Sprint, as it has the clamp screw style, and I'd like to have better posture when reaching my keyboard with the wheel still attached.
I've cracked a couple open and due to such narrow space, you will need to hand-solder a data cable from the wheel's back lid where the hand pedal pots and buttons are located, and have heat shrink tubing on hand, then possibly hot glue the wires down conveniently. Crimp connections and solder-seal are no go for this one; not enough room. It only has 4 buttons and the pots need to be completely rewired, but if you have the right tools it should theoretically work.
The initial colors for the wires on this wheel, at least the buttons, are as follows if you look closely at the picture:
Ground - Red (daisy chained from purple wires)
Button 1 (top left) - Yellow
Button 3 (bottom left) - Brown
Button 2 (top right) - Green
Button 4 (bottom right) - White
I think I was using too large guages of wire on my first attempt. Probably better to use smaller wires like those in a PS2 controller cable.\
Edit: I did recently get this controller working using hot glue for the cable. Sturdy and mostly works a charm. Though it does not have a lot of buttons it is definitely a wheel worth modding if you want a comfortable pedal-free wheel that you can clamp to your desk. I absolutely love this wheel!
