Hello all, first time post here about a stereo install question. I have a 2004 F150 with the factory stereo. On the back of the stereo there are 2 plugs, I am installing a Boss double din with touchscreen an nav. My question is: I have been looking at the wiring harness adapter so that I do not have to cut my harness, the package comes with 1 plug adapter that has the power, ground, speaker wires, etc. What do I do with the additional plug on the actual vehicle harness? Do I buy a separate connector and splice that into the other and connect it to the new stereo or leave it disconnected? I do not have the factory sub by the way and the new stereo's extra connection on back is all RCA plugs of which my wiring harness has none of these? Can someone give me an idea of what to do here. Thank you and this is a great thread.
If you don't have a factory sub then it isn't for it. Do you have a factory 6 - disc player? Either way just connect the one.
