i wasnt really sure where to put this but it is being installed on a f90bt unit so why not here right?
i bought a used p10hd hd radio unit and it didnt come with the power harness for it, so i robbed one from an old power supply for a pc, and now i need to know which of the four pins are positive and negative? or whats the proper way to hook it up? also, i looked at pics of the normal power harness and they have black boxes on the power leads, im assuming its a fuse, or is there more to it?
