not a mustang question but I got a new radio for my dad's '68 Jeep and it doesn't have a constant power line to the stock radio (or a ground line LOL) so what's the best way to wire one up? I'd rather not splice into the igntion, can I run a wire straight to the battery? is there anything I need to be careful of when doing that? Should I put a fuse in it? I put a 10A fuse in my '89 Jeep that came with my last radio even though my radio has a fuse built into the back of it.
