Did you ever find out anything on the extension harness?For those looking for a way to connect the factory foglight jumper harness without splicing ...
DIY: Add 2013-2017 OEM Foglight Wiring
We now have a "Foglight Extension harness" that I have sent out to Deereguy to be tested in his 2016 2500 truck to help finalize a write up/install instructions. Next will be to build one for my 2013 1500.
This will allow you to buy the official Mopar Foglight "Jumper" harness that goes into the bumper and plug in the "Extension" harness that will install in the factory connector under the PDC. As close to the factory wiring as you can get.

I have a replacement bumper with fog cut outs, factory style fog lights, wiring jumper, headlight-fog light switch for the dash but I sure could use the correct wiring diagram. The link to the wiring diagram posted previously here no longer goes anywhere.
