I did this to my truck with the Flex a Lite 282 kit. It supposed to move more cfm than the factory fans. I replaced the ac pressure switch with a 3 wire pressure sensor and used the EGR 5v to work it. In doing that, I can tune both fan stages to come on at set head pressures. I attached the wiring diagram I drew to build mine off of.
