2011 SuperDuty XL - Adding OEM TBC & Upfitter Switches?

[mchottie]

Where i'm at:

removed center trim, removed lower flip out cupholder, removed radio, unplugged all male plugs & wire harnesses from connectors. also removed lower trim under the steering column.

OEM TBC was cake, unplug male connector from dummy coin holder, plug directy into TBC. (i've been told this will also require a dealer flash to active?)

Upfitter switches installed into center trim, here is where it gets tricky.

I can't for the life of me locate the male plug / harness to plug into back the upfitter switches. None of the removed male plugs from the center trim match up to the upfitter switches female plug on the box. Looks like 8-pins within the femal plug on the back of the upfitters.

Any help? I have a feeling its staring me right in the face, but its 10pm and i'll snap pictures of my progress in the daylight if no one can help me this evening.

i'm going off this Ford Diagram, but nowhere does it state what to plug into the back of the upfitter switches themselves. Only thing I can think of is maybe the XL is no pre-wired? I'd have to assume all superduties have the same wire harness and the male plug is in there somewhere!!!

Not sure if it will help you or not, but when the trucks come pre-wired, the stub ends of the wires are located along a bundle of wires to the left (as you sit in drivers seat) of the steering column, about half way between dash and fire wall. They are pretty hard to find as they only stick out of the bundle about 1-1/2" or so. If they are there (4 wires with heat shrink cap) you might be able to follow them to your missing plug.

Yes, I do remember someone else installing the BC and had to get truck flashed.
