Trying to install a brake controller on my 2002 land cruiser and found this plug on the frame behind the left hind wheel. I bought a 2002 landcruiser EWD to map it out, because the plug has a couple thickish wires that seem like they go to the drivers footwell area and would be perfect for an easy breezy brake control install with just some soldering at the back and splicing in the front and no penetration of firewalls or running of long wires, but the plug is not in th EWD or I'm too daft to recognize it.
