Late model heater in my 1985
I was just wondering what I have to do to wire up my new heater and controls. I had the older 110 style heat/ac setup and am changing to NAS type. I have the harness that attaches to the controls, and the 3 wire plug that come out of the heater.
Control harness wires are: 1)black 2) green/yellow 3) green/gray
Heater end wires are: 1) purple/greenish 2) green/yellow 3) green/gray.
Unlike the NAS trucks, I believe my 1985 90 lacks harness that ties the two together. I was wondering what I have to hook up to get it to function like its newer relatives? where do I get the juice?
It seems the heater is out of a late model 90 2006ish.
