A dealer or a previous owner may have added your manual fan switch if your chassis number is under 1900.

Blas, On the wiring diagram it shows a brn-blu wire coming off the thermo sw. to the relay but on mine there is just a jumper between the two relays with a brn-blu wire. Any ideas on what color wire and location to tap into to complete a circuit to the fans? Thanks...#1721
