yes, i believe we are talking about the same thing. the electronic box and ballast were the same for all electronically controlled mopars (the color of the boxes designates rpm limits)..hope this helps. if the 5 ohm side and the 1.2 ohm side are reversed, the engine will still fire but you will have virtually no spark . with the engine running, pull off one of the plug wires at the cap with a pair of insulated pliers ,and with the wire about 1/2 inch to 3/4 of an inch away, you should get a definate orange/blue spark, if you are getting no spark but the cylinder is still firing when you put the wire back in the cap, 98% chance they are reversed. you could use an ohm meter ,but i like see that spark jump so i know im good there. i would also first ,spend the 5 bucks and get a brand new ballast.
