On the fuse box inside the car right above the rows of fuses there are several ports that are unused that show voltage when the car is on. What are these ports for and which fuses do they go to??

 

the acessory ones? you can use them for power if you so need it

 

Yeah there right above the other fuses and have prongs sticking out. But which fuse/s is the one for them?

 

dont think there is so always in an inline fise if ur gonna use it

 

If you use them, you can put whatever fuse you want to in them. Say your doing led's or something simple, might want a 10amp fuse. if your going to wire something heavier up to them like video or audio, etc, might want a 20-30amp.

I haven't used them before myself, I always find a way around it, but whatever fuse you put in there will be the breaking point for the circuit.

 

I wouldn't use a fuse bigger than 1 or 2 amps for LEDs. LEDs only need milli amps.
