I see part of an identifying sticker under them that looks like the top is a battery cutoff switch, then two automatic reset circuit breakers, and a common relay that may be for your sanicon, if I'm reading it right.
The two breakers are bridged, so they are just inline to the wire clusters on each of them. Not sure if this helps, but I tried.

This is pretty straight forward and says what each line is on the diagram/sticker.
Questions before explanation:
1. is this a 30amp or 50amp power center/trailer?
2. are you trying to specifically map out or identify something?
Battery Disconnect switch:
The sticker is lying a bit from what I see.. What I mean is there are two solid red wires coming into the battery disconnect switch. One is from the batteries the other has to be coming back from the converter to allow charging of the batteries no matter the setting/orientation of the batted disconnect switch. If this is a WFCO 8735 (30amp) power center this is a unique setup that was made by WFCO for Jayco and Airstream. Mine had this as well before I swapped out the power center.
Red wire with white stripe, connected to the battery disconnect switch, is the 12v connection going to your power center. This is the main source of 12v power for the trailer.
Directly connected, not controlled by the battery disconnect switch, are the following auto reset 12v circuit breakers:
First breaker (closest to battery switch) The bigger black wire comes in from the solar prep/panel/charger to allow for charging of the battery. The smaller black wire would be for the sidewall solar prep port.
Second breaker. Are for powering the breakaway switch to ensure it always has access to battery power.
What I don't know as mine does not have it is what the relay is used for... maybe something to do with the breakaway switch?
They are just using smaller wires as the "buss bar", on mine it has an actual piece of copper bar there..
Thank you Tom C for all this information. I'll sit with your info and my wiring picture and label everything. The relay is apparently for a sanicon system for dumping your tanks.
Hi TomC,
The 3 black wires to the 30 amp fuse are:
1. Charge line from the vehicle
2. 2 lines to the slide controllers
Does anyone know what the device is that is mounted about the slide controllers?
It looks like a version of the Jaysmart light controller without the housing. It adds features to the side marker lights. My Jaysmart light controller is mounted right next to the Schwintek slide controllers. If you have Jaysmart trailer light features, then that is probably the Jaysmart controller.
