[SOLVED] XVM279BT Mystery Wire for Subwoofer

[Ra7eN]

HI ALL!!!
Ok, I have a 05 F150, and someone installed a XMV279BT. The wiring was horrible, so stripped it all down and redid it all from scratch.
Now everything works great!
I have another adapter that is for the sub-woofer. It has 2 RCA jacks (red and white) and two blu/white wires attached together. Note: In the picture the wire is hooked up wrong - looks like they tried to hook it up to the antenna.

What wire should I use to get the sub-woofer to work. I have the 1.5k resister I know I need to put inline, however, what is the wire to connect to?

OK, I kept on searching for the answer - found it!
I was able to find an exact wiring diagram for my XVM279BT
APPARENTLY the blue wire acts as BOTH a power antenna (which I do not have) and the amp!
I think that solves it.!
