73 dart swinger heater wiring

What "diagram" do you have?

Go to MyMopar and download the two sections of the 73 shop manual, which, by the way, happened to get there from efforts on some of the guys here at FABO

Some of what you need MAY (in years past) be in the AC/ heater section of the book rather than the section 8 wiring diagrams.

Alert: The 73 diagrams are "different" and may be more difficult to follow. You can also download the 72 shop manual (also came from here, AbodyJoe) and leap back and forth, may make things easier to follow.

I can post little snips to help you along

One help on the 73 factory diagrams is to use the index, and the illustrated connector diagrams, which shows the shape of the connector, the wire color, as well as approximate location in the car
