I'll hazard a guess that red and black are power leads. They are
fairly standard red being positive and black negative. The yellow one
could be for either a temperature sensor coupling or possibly a motor
speed control. That's only a guess though and I'm more inclined to go
with the speed control option.
I am only human, please forgive me if I make a mistake it is not deliberate.
Xmas may be over but, PLEASE DON'T drink and drive you'll make it to
the next one that way.
