Do you know which color wire that should be connected to R15 and to R15/1?

I just want to make sure I do this right the first time...THANKS!
As MB Doc said, it's a series circuit. To see this 'visually', look at Menu#18 to the sketch just above the "blue" table (Aux Fans Activation).

The first sketch shows a 'three-speed' system; if you look carefully you'll see an 'extra' wire that goes to R15 resistor. There's no "jumper" bar.

The second sketch shows the 'two-speed' system. Note the jumper bar and only two wires. . . a 'series' circuit.

The resistors are switched in (shown in the schematic) with the Aux Fans according to the following;
"no-resistors-in-series" = High speed
"one-resistor-in-series" = Medium speed
"two-resistors-in-series" = Low speed
