Are they important and what do they do???

 

Have you followed the wires to see where they go? Likely an aftermarket stereo or amplifier. Fuses are designed to protect your equipment and prevent fires in case of a short circuit.

 

i have yet to do that. there is an amp in it but not sure if it works. the cable is hot and the fuses keep blowing when i try to put in new ones

 

Ok. What "Doesn't" work when the fuse blows?

 

Is it a fairly thin red wire? $100 says it runs to that amp.

 

everything still works when it blows

not really thin but it is red

 

I have this also, they are about 1/8" thick. This is for a stereo hookup for the amp. My radio works without this hooked up, so I figure it went to the amp and speaker the PO had in. It has a little housing it goes into, fuse is most likely a 30amp right? I have to agree, this is most likely speaker wire. Mine runs through the passenger fender with all the other wires making it some what confusing at first. I plan to remove all this extra wire when I do my new floor pans, carpet and seats.

 

Like the guys said, you'll need to follow the wire to its destination. If it's powering that amp, there's a chance that the amp is blown or miswired.

ok so if fuse blows when i put a new one in the amp is blown?

 

When you put a fuse in and it blows, whatever is connected to the end of the wire is bad. Or the wire is touching ground somewhere. That you will have to find yourself.

If everything still works when it blows then don't bother replacing the fuse. You're just wasting your money. Cut it off and leave it off.

 

Thanks
