[DeTomaso] Fan light in speedo w/fan relay mod

[Joe Jaffoni]

Thanks Mike - my car has the yellow wire in the harness. I'll put it on
terminal 87 and run another wire from there to the positive side of the fan

     Joe,
     Simply run a wire from the output side of the fan relay that comes
     on second, to the light (along with the wire that goes to the fan of
     course). Only the very earliest cars had this wire in the factory
     harness. Most people have to string a new wire.
