you'd think that the coil neg post (circuit) would be getting opened/closed (to ground) the same whether it points or ECU doing the job but yeah swap the wire & if that dont do it then spring for the adapter

and it says run it to a positive that only gets power when ignition is on, and to engine or chassis ground, so having it run to the dash may be the problem. It was on the negative side before and didn't work there either. If anyone can remember where you ran tour wires ( e.g red to fuse block accessories terminal)please post, it would be helpful. I'd T into the heaviest switched 12V wire (hot only when key is on) such as the heater that you can see in the fuse box & tap into (T) before the fuse (such as heater) on the back side & then solder a wire out from the T then run it on to the tack red wire. This keeps the heater porotected with the 20A fuse with no extra draw on that circuit & you are protecting the tack with an inline seperate fuse (ask Sun what they want/maybe 5A)

We wired another Sun into the Duster,to see what would work,red to fuse block,black to dash frame,green thru firewall to coil,works like a charm. Will play with the white later. I got thee yach in the Dart unwired and I am going to wire it same as the Duster later this week. Thanks again for all your help everyone.
