Curious about this

After a fashion, this IS SHOWN in the factory service manual. You can download one free from MyMopar. The 73 manual, as well as a couple of others were provided due to the hard work of several members on THIS board

Page 8-167 or thereabouts shows the connectors, CE36 and CE38. The diagram, as such, page 8-154. These can be more difficult to follow as they are not laid out like the old style diagrams

In the wire diagam (top) CE36 is one end of the adapter, which hooks to the distributor. The other end of that adaptor is one of the two in the diagram CE38. The other half of that is in CE38, hooked to the "main" harness

I don't know.........maybe the factory effed up and manufactured a whole crapload of harnesses that were incorrect, then added that little jumper to reverse them. "It would have made sense" LOL if they were simply an extension, that they would maintain polarity.

Here's an interesting tidbit for ya. I've never figured this out .....from my Motorola / E911 days (installing 911 radio telco gear) a typical wall to instrument cable for a phone (RJ11 cable) also reverses polarity from one end to 'th other.

Take a look........the center pair, red and green, are reversed from one connector to 't other



Maybe pishta knows, he's a phone guy.............
