How to wire up a 2 speed Ford Taurus Electric Fan The relays I used is the Zettler AZ979-1A-12DE for low speed and AZ979-1C-12D for Hi Speed. Than use a 30 amp relay for A/C. The Diode part number 1N5408. Make sure when installing the diode it installed with the band on the diode facing the fan. If installed backwards the fuse will blow as soon as the low side fan kicks on.
