Is this a?
It this just a 12v bus bar on the square bodies?
It appears a previous owner ran a 12v + wire from this bus bar to the 7 pin trailer plug in the back of the truck? Ideas on why they did this? They ran the red wire with the white fusible link in it. (yellow arrow).

Re: Is this a?
If the arrow is referencing that red wire at the top of the stack, that's not a fusible link. Those white cylindrical shaped objects are inline fuse holders. There's a common glass fuse inside.. As for the wire going to the 7 pin plug at the rear -- it's anybody's guess, but it could be to provide constant power source on a trailer..

Re: Is this a?
could have been hooked to a camper that usues 12v batterys, driving would help keep them charged....Dad had a popup camper that was wired in a similar fashion

Re: Is this a?
Thanks you, pretty much confirmed what I suspected. Just kinda strange...

Re: Is this a?
Pretty common for one pin on a 7 way RV connector to be constant power.

Re: Is this a?
Here's a link to a typical fusible link..
https://www.4statetrucks.com/air-ele...ent=Ad%20group A fusible link is a wire made of a special alloy that melts in to when overheated.. The link is typically a gauge or two smaller than the wire it's protecting. |

Re: Is this a?
The black wire toward the bottom that runs into the cylinder looks like a factory fusible link. The wire on the other side of the cylinder should be larger.
