Thanks to Tim Smith for sending me this information via e-mail. The YHA 208A switch was fit to the 1975 Yahama XS 500, 1976 Yahama XS 650, and other Yamaha years and models, I'm sure. In Tim's own words:

I recently needed to replace my stock 79' G5 left side switch gear. I had an old Jap type switch many guys have used before. It's a Yamaha 500 switch with just a horn, L-R turn signals and Hi-Lo head light. No Flash feature.

My replacement switch is a Yamaha type metal housing with no ground wire attached. I'm assuming it grounds it's self to the handlebar. My old stock unmolested G5 switch gear harness plug had one empty hole where the pins are. Some I have seen have two. This is my splicing chart.
