1. You cannot buy the plugs
2. There are 3 parts to the system
1. The motor
2. The harness from the controller to the motor
3. The Controller
3. There may be 4 parts. SOME use a 7 foot harness from the motor down the rail and then run the 25 foot harness to the controller. So, you have 2 separate wire harness instead of one and 2 things to fail
4. I have NEVER attempted to run a continuity check on a Schwintek harness. BIG waste of time. I have a test 35 foot cable and I connect between the Controller and the suspected motor. IF it works, then the harness is BAD. I have replaced numerous harness that showed NO damage but were defective internally.
5. Motor One and Motor Two. How did you determine which was motor 1 and motor 2? There is NO standard for which motor is which. You have to disconnect one and see which side operates to determine Motor 1 and motor 2 on your RV
6. WHAT code did you get originally? 8?
7. If you have replaced the motor and controller, WHAT would you figure is the problem by reading item 2 above????? Doug
