C-4 owner

I have an 88 here,non bose car and it looks like the reciever is behind the passenger seat in the hatch storage area.The black box has an antenna conection,4 wire power lead,and a black(looks like a computer cable)cord.I want to install a normal pioneer 1.5 din receiver.How do I deal with the antenna lead being in the hatch?Where is the power for the power antenna?Do I need any of these other wires up front for the pioneer system?

you need to extend all of those wires up to the front and get an antenna extension
