Rear Brake Light Switch

[CB750K603]

I'm replacing the rear brake light switch on a 750K. Does anyone know where the spring connects to the brake arm?  I failed to notice exactly where it was hooked onto when I took the old switch and spring off.

Thanks!

Well on my 78K, there is a little tab with a hole in it that the spring connects to.

On my 750F it hooks to a cut in on a tab comming off the brake arm. Mainly saying that some place almost if not exactly in line with the switch there is a place for it to connect to on the rear brake arm.
