Dual fan low speed wiring

[oskie]

Guys, I need help about wiring my dual radiator fans and aircon condenser fan. My current wiring is that my dual fans will only start when the water temp reach 85 degrees Celsius(activated by a thermoswitch in the radiator). Now, I need these dual fans to run in low speed when I turn the aircon system on, so this means the aircon condenser fan and dual radiator fans(low speed) running at the same time regardless of the water temperature. So how do I wire it? Correct me if I'm wrong, I believe I need to use a resistor right? Thanks in advance.

Look at the Factory Service Manual if you have a copy.

i don't know which fan controller you have, i have hayden 3647. And on that unit is a green wire, that green wire is for a/c. What it does is, override the temp sensor. So when you turn on the a/c the fans operate regardless of radiator temp.

Side note: it also operates the fans when, defrost is selected or when selecting high speed on the thermostat.
