Nope...

But you can wire in a switch yourself and turn it on/off whenever you want like I did. I used an on/off/on switch. The "up" position turns on the primary fan, the "down" position turns on the primary and aux. fans.

Yeah, but I don't want to be at 160* all the time.. that's not good for the oil.

I got mine at ZIP #PM-174 $18.95. I use it with a 180deg stat. Most other places want to sell a wiring harness with it for twice the price. You can connect the two fan relays at the green wire and do the same.
