Thanks LeftieBiker and knightmb for the help! Hosting on Imgur did the trick for me. It took me a bit to find the the BBCode. I found that from the gallery view, I needed to go to the three dots
(Options Menu) then select, "Edit Post", then while hovering over the image, go to the three dots
next to "Copy Link" and select "Get share links".
Here is what my setup looks like, never mind the dust.
BTW, one of the fuses goes to the trickle charger, the other goes to the trailer lighting module.
I'm still hoping for some details on which relay I should replace. I think that replacing it is likely an inexpensive attempt at fixing an annoying problem.
