12/71 blower motor wiring help

[timsz]

I have the Honda blower motor upgrade for my 71. I see other posts where your not sure where the wires go. Is there any updates on these wires ? There is a black wire on the connector marked 2. On the connector coming off the motor that connects to the connector marked 2, there is no black wire. Does the motor need a ground ? I wired it per upgrade directions. That was quite awhile ago, though. There is the small 3 pin connector also. It only has 2 wires going to it. Red and blue. Any help with these wires please ? Thank you very much.
