alright i have a 2002 maxima that came with the bose system. my friend gave me his wiring harness, but it only has two inputs for the sets of wires. i have three sets of wires, so one of the sets was just hanging there. we got power to the head unit, but no sound. I've been looking up on the pac bose converter and was wondering if it adds another input for that third set of wires? also, my friend has a bose converter for his 99 maxima, but he doesn't use bose at all anymore. would his converter work in my 02? or would i have to buy a whole different one to use my bose speakers using the pio prem deh?
