1G Is brake switch capable of runing vacuum pump

[GSX_Dan]

Wondering if I need to add a relay to run a vacuum pump (audi) on my auto. Right now i have the 12v from brake switch going to pump and it sounds healthy, not blowing fuses. It's been like this for a while but I don't want to burn out the switch over time if it's not rated to handle that kinda load.

You'd likely be better off longer term using that 12v to switch a relay and let the relay with a direct battery connection handle the high current stuff. That's a relatively straight forward install and pretty cheap. I'd suggest going that route.
