1980 elec fan mystery

[Tony Gordon <tgordon@saginaw-city.k12.mi.us>]

As my sons Spit gets closer and closer to being a daily driver, one problem 
has me beat.  I cannot locate the electric fan relay for this beast.  I 
have found a wiring diagram (thanks to a fellow lister), and it shows the 
thing, and spitbits even shows what it looks like, but just like Blaster 
Bates "dynamite joke," I know what it is, and I know what it does, but I 
don't know where to fid the bugger!

Help needed!!!

Thanks

Tony
