I drive a Demon (and not the other way around)

Since I found
I decided to try the lower cost Painless route. Brought in a Mopar harness. It comprehesively rewires the car and offers a neat solution to the bulkhead oonnectors through the use of plates. It also has a modern fuse panel with Mini and ATO fuses in it. It also provides for the installation of a modern radio. It does not have connections for remote turn signal lamps nor for side marker lamps, and no REAR AIR or map light switch provisions. While some sleeves for the wires is provided, it is something the user applies after the fact. Because of the variety of models the kit will fit, the end user must cut wires and terminate the ends. I could not see a happy ending to this, so now I have to go find an OM-style dash harness. I will find out how well Summit Racing's return policy works. But wait, there were two harnesses used in 72 Dart/Demon dashboards. I now have to find when the running change was made, when the Demon was built, and is the stock cluster PC board on the cluster in the car?
I have not deficit financed any work on the car, so for now, I await news from my bank that Summit accepted my return and credited the card. Not to worry, I still will need to do a bit of interior work that is stictly mechanical in nature.

Feel your pain, electrical systems is always one of the biggest challenges, Summit has always been great with returns in my experience. Keep at it, like you said, plenty of other things to keep you busy in the meantime.
