Towing switched power - R3 connections

[simonwood]

Looking at adding an ancillary socket to the main towing socket. Looking at the wiring diagrams R3 is intended to switch that power, and it seems to have all pins installed in the fuse box (although obviously no R3 installed)

Anyone know where that switched output ends up. Can borrow a tracer, but not for a few weeks. Van is a 2011 lwb with basic loom.

Thanks in advance.

It goes to a multiplug below the fuse box clipped to the chassis rail above the gearbox

Excellent, thanks. Will have a look tonight.
