There is an 8 or 10 pin female plug with a cap that says 'DIAGNOSTIC CONNECTOR' on it. My understanding is this was one of the earlier attempts at computer anaylizing, and they were in the 79 and 80 models, adn probably in the Dodge Ramchargers as well. I've had electrical problems FOREVER, even after replacing the wiring harness.
I'm trying to find the tool that plugs into the plug, or at least what it's called to help me searching for one.
Ah the good ole lean burn years. Most folks I know pulled the lean burn stuff, then reverted back to the basic electronic ignition from the 72 to 76 era.
Maybe a trip to the local library to checkout the MOTORS maual from the era might answer your questions. Or check with summit racing for a kit that replaces the lean burn stuff, that lean burn system was cursed as junk by all the Mopar techs of the era.
If you have a Dodge or Chrysler Dealer that has been in business for a long time, it might be worth a check with them to see if they still have the Official tools from then. I know that the parts department at the dealership I worked at for a while had all kinds of testing and other special tools issued to dealer service departments. Don;t know how far back it goes but most of those old school guys don't ever throw anything out.
There was a Lincoln Merc Dealer in town here that went out of business last year and had an auction to clean out the building, they had stuff that went back to the late 50's in the tools that were being sold off.
After I retired, I took all the automotive classes (48 credit hours) that the local junior college offered. Our engines instructor referred to those years of MOPAR computers as "shake & bake"; he said, "What's the two worst things for a computer?" (heat & vibration), so where did Chrysler put their computer? (on the air cleaner housing, where it would be subject to heat from the engine & vibration).
I drove a 1980 Dodge St. Regis (360 engine) when it was new, and the computer would heat up and kill the engine in the summer. As soon as it cooled off, the car would run fine for another hour or so, then the same thing would happen.
