Wiring up overhead console

I finally got an overhead console but i am wondering if my Pioneer has the harness or atleast part of it already. Ive got a 1990 Pioneer and I got an overhead console out of what im guessing to be a 1992 maybe. Just wondering what mods i need to do. Any help ASAP would be appreciated.

Found out ive got a pink,black, and black with white stripe wire for my dome lights. The overhead console has a whole lotta wires though. I went back to the junkyard today and got the plug that plugs into it and there are 14 or 15 wires. I need to know which ones go to the overhead console. I realize i will need a temp. sender but i have no keyless entry cause its a Pioneer. I really need some help ASAP. Thanks a lot.
