HI S5 headlight switch PCB layout

Hello, I'm wondering if anyone has taken photos of their S5 (FC) headlight switch cluster PCB when fixing it? Perhaps you are wondering why I'm asking...







A friend's FC headlight switch apparently blew up when something went wrong. I've read through several headlight switch fix tutorials, however Mazda must've had running updates since both of the writeups I saw had a different PCB layout than the one I have, and each other. The car he has is a 1990 GXL from Hawaii.

If anyone has the same PCB revision as the one I need to fix, would you please share a picture of the PCB or trace the connections so that I can solder patch wires to the proper place? I have managed to get a temporary relay-based fix based on trial and error (and several blown fuses), but having the peace of mind that the connections are as they were originally engineered would be appreciated.

Thanks! (:
