Does anyone know where it is located on a MB 24? And is there any fix for the DIY’er?

I have not had this issue, so the following is sourced from this forum. "Use at your own risk".
Assuming the Murphy Bed version has the module in the same place as the "S", see this thread:

If you are lucky, maybe you just blew a fuse on this module hooking up your Toad. Post #16 by Pedrodasdas on the "Running Lights Gone" thread shows a picture of the module and its fuses.
There are also several reports of uncrimped wires, a short from a screw through wires, flooded taillights, etc causing this failure and not involving a failed module.
If your module has failed, as to a DIY fix - I've noted three of interest:
1) lowandslow has posted a great work-around approach using the trailer connection. See posts 80, 81 and 82 earlier in this (2010 Solera, clearance and rear parking lights) thread. He has even added a trailer connection. I carry a trailer plug with me "just in case". Inconvenient - you have to unplug the connector to turn the lights off - but a GREAT emergency countermeasure.
2) peterfinurke successfully repaired the module by replacing a defective relay on the board in the module. Running Lights Gone thread linked above, post #54.
3) emilizik reports earlier in this (2010 Solera, clearance and rear parking lights) thread, post #11, that a Mercedes mechanic successfully bypassed the module with a relay.
Should my unit fail, after getting home with lowandslow's workaround, I will likely try this last approach. I believe a 12 volt relay connected with the coil wired between the "park in" wire and ground, and the contacts wired (fused) between the "brown wire" (running lights) and the 12 volt power input wire to the module should work.
Would value comments - particularly from Gyasi.
Let us know how you make out -
