Ability to add Hill Decent?

It is JHD.

I just have found out that this feature is listed at the RPO vehicle’s codes sticker. Look for it
(JHD) HILL DESCENT, GEAR HOLD

Yea I think you are right. Even on the Z71 it is JHD.

I added the switch when I found the wires. I don't think the BCM is programed. Can HILL DECENT be programed in?

Did you make any progress? 
 

I finally got a full RPO list for mine and JHD is not on there. 

When you said you found the wire , was it behind the switch just not plugged in? How did you get the trim and switch off?

It was in the harness already. With out the switch it doesn't go anywhere. After I put the switch in it still didn't work so I figured that the BCM might need to be programmed. I spoke with WAMS and they said it looks like it could be done but wavers would have to be signed for the liability with being linked with the brake system.
