Where can I find a transmission wiring harness ? P0870, P0760
 

I've looked on ebay, local scrap yards (not that Id trust one from there), the MOPAR parts site says its discontinued.... Ive been through the ringer with this thing. Ive replaced the solenoid pack 3 times thinking I kept getting a bad part, im pretty sure its actually a bad spot in the harness somewhere. I keep getting p0760 and p0870, along with hard shifting and occasionally limp mode. Then I have to turn it off, plug in my code reader to reset the codes , and Im off again. As long as I shift in sport mode and take it REALLY slow and easy, it gets me back and forth to work. When I did the solenoid pack, I found no metal shavings in the pan. Fluid looked pretty good overall. I REALLY feel like this is all due to a bad wire somewhere. If anyone has any ideas of where to find a harness, PLEASE let me know.

missing some vary simple information about the car.
