I just installed the non ac box and I noticed that the factory plug fits it but doesent work. Before I bust out the test light do I just need to rewire it or do I need to add non-ac controls in the cab. TIA.---EDIT--oops wrong forum--shoulda posted in chassis/electrical
Take the resistor assembly off of the original A/C heater box and install it on the new non A/C box. THe wires may need to be lengthened to fit.
This is by far the easiest thing to do.
