Refrigerant Type: 134a

Hi, I have a switch for the high side and want to be sure before I plumb it into my system. Ford Taurus 98-01? V6, switch # YF1H 19d594 AA
I hope to use it for a containment switch and to control a relay for AC cooling fan on my R134a system on a 2001 F350 with the 7.3L engine.... Looking for N.O. and N.C. and what pressures? Thanks, Artie

Three-wire devices found on late model American cars are usually a sensor. They output a voltage or digital code, proportional to pressure, to the ECM. The ECM then decides high and low limit and fan trip point in software. The typical old style fan / HPCO switch has 4 wires.

That's what I'm hoping for, my switch has 4 wires, I have the Hi cutout pair wired in, and I hope the other 2 will close when the pressure goes high? Hoping my value will work for my electric fans, Thanks, Artie
