The black wire you use for the ground, should be as big if not a little bigger then the one that comes out of the factory harness for the taurus fan. If you used some kind of connecters for the connections vs not using soder....check to make sure all of those are tight. I just had mine quit two weeks ago and a bad connection (my fault) smoked the connecter.

When the ground wires get that hot, that is a sign that the wire is too small.
