Kassan1973 Posted July 1, 2020 Report Share Posted July 1, 2020 Hello i have some ford el fans with low and high speed and wanted to know the easiest way to set up low speed relay to turn on at 70 deg and high speed relay at 90 deg , will be switching a earth to fan relays, and then also switch high speed with AC compressor on , im using a G4 extreme which is currently just switching a aux output high speed only with no AC switching.
