Raptor line output converter

I got a raptor LOCA25 lone output converter but not to sure how to hook it up. It didn't come w/ instructions. Im hooking it up to a stock '04 chevy .

YOUR GONNA TAP THE SPEAKER WIRE SIDE OF THE LOC ON TO THE REAR SPEAKER WIRES TO CATCH SIGNAL. IN CHEVY YELLOW AND BROWN IS REAR DRIVER AND BLUE AND LIGHT BLUE IS REAR PASSENGER. YOU CAN CATCH IT BEHIND THE RADIO OR IN THE DOOR SILLS. THEY WILL BE TWISTED TOGETHER. HOPE THIS HELPS

so does the brown wire off the LOC become the remote wire??? On one side it has the speaker wires and the other side RCA's and a single brown wire. 

No, you will still have to get switched power from the turn on wire behind the head unit.  Just cap off the brown wire.
