I just installed a stealth hitch on my 2016 l405 and Im trying to figure out how to get the trailer dash light to come up on the cluster. I used my gap iid tool to activate everything for it to pick up the trailer when its hooked up. The trailer does have led lights so I bough an adapter from Curt to take care of that. Still no light on cluster when trailer is hooked up. Am I missing a seeting in the CCF? Thanks in advance for any help
