what sized inline fuse did you use if any when you tap into your 12v keyed source?

 

i use 30 for most everything

 

30's for nitrous and fuel solenoids..
20 on the purge..
30 on heater,

Really...its all overkill... But I'd rather have too big than not enough...
Also... Does you no good if you don't use big enough wire...
10awg on anything 30-40amp
12 awg on the 20 amp.
