Had an mei in my machine and am changing to a uba 10. Installed the unit and tried jumpers on the backplane J1 2/3 J2 1/2 and J3 2/3 and also tried J1 2/3 J2 2/3 and J3 2/3 but can not get the unit to work. I connected it to the tool suite and it had id003 and I even flashed a newer version on the BV. The red light is on but unit does not cycle. It was tested working by a seller here on NLG. My question is what does the harness look like and want to make sure I have the correct harness. The harness looked to be brand new and when I got it the harness was packaged.
