factory AC wiring question

[kensousa]

I have a '71 with factory AC that had been taken apart by the PO.
I think I have most of it put back together with one exception.
Under the dash,on the passenger side of the cab, I found two unattached wiring connections.
One was a two wire connection that went to a switch driven off the AC cable and i found that one.
There is another 3 wire connection that the schematic shows going to a resistor. I think the colors are green, pink, and yellow.
Can anyone tell me where this resistor is, or should be, located?
