It seems to me that somewhere in the settings you have to enable the remote engage switch.   But it’s been several years since I last installed a remote engage switch so that may not be correct.  


If it’s never been used that could likely be what needs done and along the same lines I’ve have setting get messed up when doing “updates” which is the primary reason that I seldom do updates unless there is a specific problem that I’m looking for the update to fix.
