where do you guys get your switched ignition source for your fans and gauges?

i am asking this because i ran out of them in the fuse block. i had my radio on one in an empty fuse slot, and i had to use it for my tach and fan. now i don't have one for my radio. (it is missing) i am afraid to run three thing off this one spot. would i be safe running all three off this one?

 

Run you fan using a relay and with the relay into the switched lug. That way it will have minimal current draw. Wire you gauge lights into the dash lights
