2016 GTX 155 fault codes not clearing (New IBR Actuator)

Hey everyone, so I went ahead and ordered a new IBR system, got it installed and I have the innards buttoned back up, but I am still getting P0546 (This code I expect to get until I hook the ski to the hose and fully start it, but the exhuast sensor is in place and plugged up), U16A4 and U16A5. The last two are IBR codes, but it keeps saying fault even though the brand new actuator is plugged up. Fuses are all good. No reason for the wiring harness to be bad, though I can explore that as a very very last resort since it's a bitch working in the bay.

Any suggestions on what I should try and look for? I have the batter disconnected and will leave it like that overnight in hopes that it clears codes, but could there be something I am missing? If I need to, I can put it all back together since I still have the prop off, and take it to the dealer and have the clear it, but I just don't want to take my skis 45 min away just to have codes cleared if there is somethig that I can do myself. Thanks!
 
A new IBR actuator need to be married to the ECU with BUDS to work properly.
Gotcha. That to me is good news. I was like electrically this makes no sense what is happening lol. I’ll give my local dealer a call and see if they can help me out today. Thanks!
