That way you always have power brakes or a warning light if you don't.

What you say is good. I have been putting off adding a warning for a while. I had my vac pump relay crap out last week - but luckily in the welded closed position, so the pump just ran constantly
I have a low oil pressure light that [obviously] isn't being used anymore. I plan to hook that up to the existing vacuum switch so it turns on every time the pump turns on. Sure, it isn't a second sender, but at least I will be able to see the pump cycle during normal driving and notice when something abnormal happens...ie..the light not going out when it should.
