DizzyDale Posted January 20, 2005 Share Posted January 20, 2005 Dear John,When it comes to anything electrical we are in the same boat.I would suggest getting a wiring diagram for the same year Ford.I would think they would be the same and more readily available.diz <img src="http://www.aaca.org/ubbthreads/images/graemlins/smile.gif" alt="" /> Link to comment Share on other sites More sharing options...
gravity Posted May 6, 2005 Share Posted May 6, 2005 HI I just wired up a 47 heater switch that has 4 wires2 wires go to the brushes and the other 2 go to thearmeture fields,What are the colors of the wires?, I believe One is black,One is red, and the other 2 are either yellow or orange.Note the Green ford manual does not show the heater wires on the schematicI guess because of the manufacture of the fan motorsI have 2 motors and the only color thats common is the black and red.The other item is "SPEEDS OF THE FAN", some are single. and some have a fast and low speed.Gravity Link to comment Share on other sites More sharing options...
