Don’t even think about it, assembling the brake switch from below. The the spring will jump away along with rest of the small parts.

Turn the brake lever upside down. This is valid for GT750 as well.

I know, the nut and the bolt for the brake lever is wrong. Will be replaced later on when I get the parts. I have to use what I have to get going.

Make sure the switch moves freely to both positions.

Add the contact disk of the switch.

Mount the plastic enclosure and make sure you have a good strain relief.

Zip ties

I use reusable zip ties at this stage for an easy adjustments if needed.
