I couldn't find a price on it but, what a clean way of doing it. my picture show hacking in to the line in 2 different place to get the job done. That shuttle valve make it simple. Basic relay wiring.
Really want to do this, but i would only do it if i had a remote cooler and fan. Which adds a hole bunch of Dollars $$$ to the project.
It's on my "to do list" but it a long ways down the list.
Thanks for the link:thumbsup:
