Anyone try using the thermo-control that's built into some electric fan shrouds?

I am using the Volvo dual speed fan relay to power my 2 spd Mark VIII fan. It works great with a BMW dual thermo switch to actuate the fans as needed. If you google the Mark VIII/Volvo/BMW you should find all the info on it.

If your radiator has the emissions thingy in the top tank it is easily replaced by the temp sensor. Alternatively, you could swap the petcock for the sender, too.

This is a short video showing my cooling setup part way through.
