Connecting Fan 2 Wiring to Auto/On/Off Switch

[layzurguy]

What I'm tring to do is connect FAN 2 Wiring (673 DKBLU 2nd picture top diagram) to
The Auto pole of the AUTO/ON/OFF switch so I can manually activate the FAN if needed.

I'm a little confused since in the 2nd pic, I don't see a Negative side to the coil on the relay.
Can/will this work?

The fan relays are "grounded" by the PCM. In other words, A10 and A11 are working like switches that connect the relays to the negative side of your source.

So...
I would connect:
A10 to the AUTO side of the switch
Ground to the ON side of the switch
The feed lead to the Negative side of the Coil

Is this correct?

Yes. That's the way it looks to me.
