Looking at the 99 regal and the sensor on the tranny and the VSS on the 92, it seems both use yellow for Ref-Hi which in your case was B10, I put this to the MS3X Cam-In. I then put Ref-Lo (purple) to the Ground, which was B9 in your case. not sure if it matters which way, but Hi would normally be signal and Lo would be sensor ground. I'll play with it some this weekend if I have time. I thought about starting over on the wiring just to be sure.
I also found this info, not sure if it helps for setting TS setting for the MS3.
