Hey guys, I’m a long-time lurker/first time poster, but thought I might post since I just did this exact mod last week.
I picked up the Wii Hori stick at Overstock since it was going for $38. I enjoyed it for about a day on the Wii, but the only game I could use it for was the SNES version of Street Fighter II on virtual console. So then I went to Lizard Lick and ordered the Sanwa JLF stick, an octagonal gate, and 8 Sanwa size 30 buttons (you really only need 6 but I figured what the hey).
Then I took PS1 H-series controller apart, desoldered the rumble motors and shoulder buttons, and scratched off the black gunk on the PCB to expose the copper based on this diagram:

Then slowly started desoldering the stock Hori buttons off of the original PCB. This was a major pain but after using a soldering wick to absorb all the solder, they easily popped off. If you don’t plan on using extra Sanwa parts, you can start soldering following this wiring guide:

Find the 4 ground wires on the stick and just daisy-chain them to the common ground.
If you do plan on adding a JLF stick, you have to do a bit of modding. You’ll need to dismantle the stick and remove the metal mounting plate. I had trouble with this because the screws holding the mounting plate were covered with Loc-tite. I couldn’t find info on how to prevent stripping screws on Shoryuken, but found that this was a common problem for RC hobbyists. The solution is touching a soldering iron to the screw head for a few seconds. The heat will loosen the Loc-tite and allow you to remove it easily.
Now look for 4 holes on the plastic part of the stick that will be mounted. The plastic bump surrounding each hole is a bit too high to accommodate a screw head so you’ll need to Dremel these down so they’re level with the surrounding plastic. Then you’ll need to cut the original screws by about .5" since they will be too long. After that, you can screw in the stick, and put on the octagonal gate.
Then I noticed that the shaft on the stick was too long on the JLF and prevented the metal panel from going back on, so I replaced it with the Hori shaft. I also Dremeled off the 2 tabs on the octagonal gate too, and now it will fit perfectly.
I left the Wii PCB in there connected to all the turbo buttons just in case I figure out a way to wire both the Wii PCB and PS2 PCB up simultaneously. I soldered everything up according to the PS1 wiring diagram and traced the Start and Select routes from the original Wii board and wired them to the PS1 PCB. The Hori case also has these annoying tabs where the buttons go in so you’ll need to Dremel those off to make the Sanwa buttons fit.
Whew this was really long. It took about a full day of modding to get everything right. It was really tough trying to find information on the Wii Hori stick so I hope this helps future modders. This was my first stick mod and it came out perfectly and now I’m in heaven playing Capcom vs. SNK 2, Third Strike, and KOF XI with the best stick I’ve ever owned.
Next up is trying to find a way to mod both PCBs up simultaneously, which seemed a bit tricky. Would it work if I just wired the buttons to both PCBs and then linked the grounds?
