OK, just look at any jack you have. IF your jacks have 2- 2 wire quick connects, then you have the updated Jacks. But, BOTH wire connects need to be connected. Also, the NEW style controller has a bunch of LARGE 40 amp ATC fuses on the control board. It is almost square and the OLD control board is enclosed and rectangular and NO visible fuses. Just trying to save you a 200 mile round trip. Yes, the 4 wire new Jacks the sensor sends the signal to the control board that monitors how many rotations the motor has turned. The OLD style board did not do that as the old jacks had no sensor on the jacks. Doug
PS, on the OLD system and you installed updated 4 wire jacks, you did not connect the sensor wires. Because there was nothing to connect the sensor too. IF you have the NEW style wire harness and Jacks and Controller, then someone has had the system updated before you purchased the unit. Years ago, Tiffin had an upgrade program at a reduced cost to update the old Atwood system to the new Atwood system. It may be your unit was one of those. Doug
Just as additional info to what Doug has posted. I had the new jacks installed in my previous coach.
Here is a pic of the old control module
And a pic of the new one that was installed
