hey guys.. i got a new SONY head unit cd player.. anyways. i searched for harness to connect everything together. the harness below , is that the ONLY harness out there??.. cuz i have no idea where to plug those 4 wires.. Black, White, BAby blue, and purple.. my sony has a White and Red , that's label for "audio out rear". and what a bout those two anntena wires(the small and big)?

well. it seems like no one wanna bother with this pose.. so i went and did my own little research .. and for all those that is having this problem on installing a after market HU..

those four RCA plugs are output plugs.. my SONY stereo had two RCA output on it. so i went and got a pair of adapters(two female and one male) and just hooked it up..

as i was looking at the RCA wires. it notice if you cut the plug off and just use the wire of the harness and connect it with the same wire that's coming out of stereo. it'll do a much better job.. cuz the stock speakers are somewhat surround sound.. or i could be wrong. hehe
