What I was told was that the UD60 used an optional Dana Spicer E-Locker Harness (DAN10021771). I had assumed this put the locker functionality back to the stock switch? Did you not use the optional harness or did you go to the spod for a specific reason? I have been eyeing the XD60/60 set up from dynatrac with the eaton lockers but to my knowledge they won't work with the OEM in dash switch. I've read the XD60 is a lot better than the UD60 but is not plug and play like the UD which is swaying me towards the UD60.No the lockers are now controlled with my spod.
