Ok havnt don this before. Can't b hard. I wired many head units. I spend my time on motors not sound systems. I bought my 97 gp and I see the owner before me had a system in it. I see the power cable with no fuse. Ik I gota put that in. in the dash ivsee a red and black RCA cable yes the ends are that color. I assume that goes in back my deck ? I then see a single blue wire. mine you all 3 run to my trunk . I assume that blue wire is for remote wire on deck?
