I have an 2004 Subaru Forester xt with the 4 spoke steering wheel. I swapped to the momo 3 spoke. The airbag activator (I don’t know what it’s called) swapped out from the 4 spoke airbag to the 3 spoke airbag without modification. All I had to do was undo the 4 nuts and it fit perfectly. Made it so I didn’t have to rewire the airbag. I had to rewire the cruz control (white to white green to green and don’t connect the yellow to the red.) Also make sure that extra ground is connected to get your horn to work. Posting this because I know someone needs to know it
