Ok this is my first post in all, but I really need help installing my wiring harness.

This is what im working with;




Also what do I do with these rca's and wire's?




Ill get a pic up of my car soon, but any advice will be greatly appreciated!

hook up both blue/white wires to the blue white wire on the aftermarket radio.
the rcas go to either the rca output on the new radio, or the subwoofer output (if its available)

oh yeah, and ground the black/white wires.

I have the same problem, trying to install an Alpine 9886.
I am using the 120705519 wiring harness from Crutchfield.
What do you do with the plug in the middle???
