Anybody know any links for Online wire diagrams & repair manuals?

I am going down the path of installing an overhead console from a 92 in my 93 and luck has it that there is no harness allready in place. The Hayes manual I have is useless in this area...

just find a switched hot from the fuse panel, run an extra long wire up the A pillar on the driver side and ground the neg. from the overhear console.. if there are more than 2 wires, chances are they are to turn on lights when the doors open (cab lighting).. If it has a compass, I would think that its directional bearings are mounted within it, so no need to hard wire it.

Thats all I know.. after that, I ask my neighbor, he works on Ferrari's..
