Banjo Bolt Brake Light Switch

[BrokenSprocketGarage]

Any Drag Specialties or Parts Unlimited Street catalog has these switches in multiple SAE and Metric thread pitches.

This is true. Make sure you leave a little slack. I just broke one myself. Had it to tight for to long.

They work great until you break the wires off. Make sure you protect the wires some how, put some heat shrink over the plastic housing it comes with.

I am about to do this. I have an 89 sporty. Can someone add some insight to this. Does one wire get grounded and the other gets connected to????

Thanks

One wire provides voltage into the switch, the brake fluid pressure closes the switch and the voltage continues it's path on the other wire which goes to the brake light
One wire is power in, the second is power out to the brake light.

they work great just keep tension off the wires as they are super thin. I usually load the shit out of the end with liquid electrical tape than shrink wrap over the plastic so it has some flex but holds it in a bit better.

I use these on all my builds. I usually put a 90 degree spark plug boot on it to protect the wires.

Harley makes one that you put the connectors on.For the rear brakes on a dyna.

not sure if someone said this already said this but there's a boot thru drag specialties looks like spark plug boot goes over that
