Jim,
Thanks for the info.
The temp sensor can be found here
http://www.permacool.com/Catalog/Cat_page19.html Part# 19003 or similar. I
didn't do the install. It was there when I bought the truck.
Use of the existing sensor is not necessary. I'd actually prefer to get a
variable temp one. What type of store would I likely be able to buy the
needed relay from?
