How do I hook up this old Kraco AM/FM 8 Track?

[sircrunch]

I bought this truck and the old radio didn't work. Its an old Kraco AM FM 8 Track Player. Pretty cool and period correct for the truck (1975) So I look under the dash and its never been hooked up. Can someone tell me exactly which wire under the dash to hook to which radio wire?

Heres what I found hanging under the dash:


There was also this coming from the single dash speaker:


And finally, this does not appear to be factory because this red wire with a half of a fuse container is stuck into a fuse in the fusebox all home-made lookin' (orange arrow) Also in this picture you can see the wiring coming out of the back of the Kraco radio.


Here are the Kraco Radio wires spread out so you can see them. Not sure why but there are 2 black wires. One goes into the white connector at the end and the other just hangs free by it self.
