Fuses are a nice novelty. look up how to use a relay online and that might make for a bit more available current. you still need to put a fuse on it with the relay.

witch relay should i hook it up to? i hate my fuse boxes. i have 3 seperate boxes.

With these kinds of questions I'm not sure you should be tearing into electrical things just yet. I would suggest doing some research on how to wire things up

 

(No disrespect, I also learn by doing, but don't blow your car up trying to figure it out on your own :thumbsup: )

You can learn an awful lot with a 12volt power supply on a table before wiring a car.

well lmp558 would u mind showing me a lil bout it when i swing that way when i get her fixed?

i mean i know how to hook it up but where it comes to like finding the hot and neutral and ground out of a 5 prong relay aint to easy

all it would take tho was for it to be shown to me once and i would get it. i havnt found a good video online that i can understand. i mean youtube has tought me alot but something this simple i cant understand. smfh.... and whats bad is i am an electronic guru. i hooked my radio up the other day and its working like a charm. now i just have to get an amp for the 12"s  i bought tonight. also got a spoiler and a hood scoop!!!!! i dont know how to post pics on here. i do on the url link thingy but i dont know how to get my pic like yalls is..

Definitely take Imps advice and practice with a power supply, I couldn't tell you how many people try to return those LED strips thinking they don't work. We don't return those for any reason if they work going out the door. I know a little bit but not enough to take on LED-ing one of my cars out. Started to on the GTP. IIRC you have to use those resistors in series with the leds or bad things happen. Surf around the site and find a few RobertSaar threads on LEDs, our resident mad professor, well one of them.

sounds like you gave the battery a direct short from it's positive terminal to negative to get that kind of reaction.... I don't know what gauge wire you were playing with, but it takes a LOT of current to get even 20-gauge wire to heat up that much. far more than what you described installing should ever draw. 20 gauge should get hot enough to act like a fuse somewhere between 50 and 60 amps. your switch is probably junk now as well considering how much current likely passed through it.

 

LEDs can be a headache if you don't understand how they operate, especially since if you expose them to too much current even once, they're toast. depending on what you're buying, that can add up pretty quickly.

 

I'm going to second the bench recommendation.... especially if you can get ahold of a power supply with an adjustable current limiter.
