It may not be used on your application.

I have a Gen IV for my 66 Elky
Have servo motors for Fan, Temp, Blend.

The harness that came with the kit included plugs for 4 servos but I am only using 3.

The plug with the white/blue wire is not used.

I'm not sure, I looked on their site the diagram is just like mine I have a four knob streamline panel, the diagram shows 3 possible servo plugs mine only has one but there is no place for it, at the bottom of the diagram where it shows the plugs it doesn't show any termination of the plugs, the rest of the wires all have a termination point shown just kinda confused as to what to do! Figured I would tap some knowledge online before the holiday is over and could contact vintage!

Your Gen II Mini system has 3 servos. Two of them are mounted on the AC case and are usually plugged in to the control module harness from the factory. The other servo plug connects to the electronic water control valve, which gets installed on the inbound heater hose.

Hope this helps...
