2017 Pilot trailer light problem
 

Hi all. Behind the left rear tail light Honda keeps a funnel in case you need to pour gas in with a gas tank and relays? fuses? for the trailer lights. The manual has absolutely nothing in it including that this panel even exists.
I shorted out the running lights on my trailer and would appreciate any assistance in identifying the 4 relays/fuses in this location.
This happened once before when I was on a trip and a honda dealer showed where it was but not what he did.
Appreciate your assistance and time.
Regards
Lambo

Access to the fuse panel is in the covered storage area, left side behind the tail light.
Even though the trailer package was Honda, it is looked at as aftermarket and not in any Honda documentation.
