-unscrew 4 bolts and lift compressor (look out for wires)
-remove plastic cover with BMW logo behind battery. Electronic bay should be in full view with unused bracket available for trailer module
-remove plastic cover clipped against body, that cover separates spare tire and body towards the back
- you should now see a hole in the body covered by a plug. Be gentle with the plug, I accidentally sliced open mine. Had to glue it to prevent water getting in. That’s the point of entry of trailer module wiring inside the trunk
- pgs 12-14 of the pdf guide posted by OP in the very first post of this thread should help you with steps by steps (part 12)
