If you have an S2, you have a 2018.5, use this reference for anything as it indicates yiu have the S2. The 2018.5 is kind of an oddball when it comes to wiring and Jayco could never supply me with a specific wiring diagram. I have these diagrams which help determine where related connections are to start looking, the basic drawing matches what is on mine, and the detailed one is from 2019. The 2019 had a separate fuse box for trailer lights in the battery compartment so maybe if yours is a late 2018.5, it MIGHT have that small fuse box, but mine doesn’t. In emails with Freightliner, this is what they told me about my chassis based off my VIN….
“ The rear lights ( turn, backup and brake lights) are controlled by the chassis module (CHM). The CHM is powered by 3 VBATT fuses. They are labeled CHM VBATT1,2&3. It then will send the power out on those circuits when requested. On your chassis Freightliner did not provide the tow plug harness only a harness for the body side to tie into for the rear lights. I am not sure how the body builder has tied in to our wiring for the tow plug. I have attached the wiring for the rear lamps.”
The fuses that are mentioned above, are in the fuse boxes located on the drivers side inner fender well when the hood is raise, so check the fuses there.
