If I understand correctly, the hot side of the coil is the (-) and the ground side is the (+), as the coil is labeled in the Chrysler manual, and the 7 ohm resistor goes between the coil hot and the PRI contact on the trans relay.
I'm sorry if this is a dumb question, especially about the hot/ground/+/-, but this is my first experience with a Pos Grd system, not to mention the harness has been spliced/repaired I don't know how many times so colors are almost worthless, and it's making me crazy. Just trying to make sure I don't screw up my trans or let factory smoke out if I hook it up wrong. lol
