Hello, I have a VERY old Pioneer BP-880 Graphic Eq/Booster that I want to re-install. The wires are as follows and are self explanatory.. Red-12v to ignition sw. Red w/ white stripe - Connect to red constant Black - Ground Blue - Has 1 male and 1 female lead on the same wire to connect to system control terminal and auto-antenna respectively. 4 front left and right + and - wires 4 rear left and right + and - wires 1 set RCA jacks The problem I have is there are also three additional wires One solid black One solid green One gray w/ green stripe I think those wires are booster input wires but where do they connect to the head unit? Head unit does not have any RCA jacks. Any info would be greatly appreciated. Thanks
