Help ID this Napa Echlin...thing.

Fan is old-school on the motor style. As far as I know the last motor also did not utilize electric fans.

I did some tearing/tracing and found that the red wire went to a spade onto the Alternator, but has been taped away. The Green and one Yellow go to some clips that were buried in more tape near my carb. There isn't any slack, so whatever they plugged into was there. The 2nd Yellow I can't find. No idea where that went.

It doesn't appear to be connected in any way to my temp sensor, other than the sweet tape job someone did.

I guess since 3/4 of the wires aren't connected, and the 4th doesn't show any voltage, it means nothing? Another oddity to add to the board, I guess.
