I used one of those pins for a connection in my 2018 wagon and do not have the upfitter switches, just the towing package and TBC. It would have been nice to have a connector to properly plug into C11-H, didn't have time to hunt one down.
WARNING: Harnesses passing through
sheet metal must be through protective
grommets that also ensure a watertight
seal. A windscreen type sealer should be
used. Adhesive or tape is not acceptable.
NOTE: Holes must permit the appropriate
connector to pass through.
NOTE: The maximum size of additional wire
bundle diameter is 6mm
There are three locations in the dash panel which
have been identified for additional holes to route
wires through. See figure E145360 (view from
engine bay) for locations. The number of suitable
locations will depend on the vehicle specification.
The grommets in locations 1 and 2, shown in figure
E145360, are molded directly to wire bundles in
polyurethane foam material. It is not possible to
feed extra wires through with the wire bundle. The
grommets have an 'indent' molded into the surface
face, engine bay side, which show the positions
where an additional hole can be made
Here they are if you have the upfitter switches. Pin 1 and 2 from the C12-A connector in the dash come out as Pin 2 and 3 of the C11-H connector on the drivers side engine compartment.
