is there anything else?

I would suggest going to an auto parts store. All around here carry several types. I used a type that was called add-a-circuit. You remove an existing plug-in type fuse and plug this in. It has one spot to plug in the fuse you just removed to restore that circuit. It also has a second space for a fuse for your new circuit along with a length of wire attached. It seems to be safe and quick. That is how I ran power for my cb radio.

these things??

i went to autozone but they really didn't have anything i could use

I used Littlefuse #FHA200BP add-a-circuit from Advance Auto Parts. I also saw it at Murray's.
