Hello CWB & DTH,
I got nowhere at my Chevy service dept. I did install the HydraStar adapter and it has been working well.

When I first plug the camper pigtail into the truck now it shows an electric brakes error but then, only a moment later, the gain controller comes up and shows my setting, 50%. It works great, no complaints. I always do a pull test before driving off to be sure everything is working properly.
When I went looking for an adapter, Dexter had just come out with one. Since the actuator is a Dexter I tried to get that one, but an 8 week backlog and I decided on the HydraStar.
I also just got the Chevy trailer tire pressure monitors installed on the camper’s tires, had to have them dismounted, tpm’s installed, re-mounted & balanced. Got that working now too (tire pressure & temp)
Good luck!
Best Regards, Mike
