the fuse i keep blowing is 10 amp, its the one in the glove compartment. my friends said try a 15amp one but im worried ill fry my radio and all that stuff but they said they head unit and amp all have their individual fuses, but that still seems like more work than necessary cause then id just have to replace those..
the connections i believe are just the copper wire wrapped around eachother with the electrical tape around it to hold it together.
as for a wiring harness im not positive i know what you mean. i have a adapter type thing that has the big black plastic piece on one end with all the little prongs inside that you have another piece plug into and on the other end of it are like 10 different wires coming out. specific for GM vehicles bla bla bla all that stuff. is that what your refering to?
