i installed a new stereo deck in my el camino a couple months back, when i got the car all the wires were cut in the and the stock stereo harness was also missing. i found the power cable nd ground. i couldnt find a cable for current power (to save the radios memory) so i mickey moused it and ran it straight to the battery. is there anywhere i can connect it in the fuse box to keep my radio stations saved? also is there a hole or do i have to make a hole in the firewall to run 4 gauge cable thru to the battery? if so where is it or where is it best to make it? sorry if it confuses you, ive been up since 3am working and im a little tired. any help would be great. thanks!
