Another Taurus E fan question
 

Hi all, I got the koyo and taurus e fan combo, Im looking for wiring options to my microtech, so far I found this,
Terminal 85 goes to switched 12V (IGN key).

Terminal 86 goes to Microtech aux output.

Terminal 30 to a fused high current source to power the fan.

Terminal 87 to the fan + wire.

Other fan wire to chassis ground.

My question is, how can I wire the fan so it can also use the low and high fan automatically, I read something about a volvo relay, any other ideas? Thank you all.

The Volvo fan relay is so elegantly simple and reliable, I don't know why you'd look any further.
I'm probably biased though.
