2018 Tow Haul button/switch wiring

Does anyone know what the wires on the back of the 2018 Tow Haul switch are? I am going to change my switch and I need to know which wires to connect to the new switch.
Here is a picture of the new wiring/plug.

@NewImprovedRon figured you are the guy with the answer.

THANKS IN ADVANCE

 

I’ve got EWD for a 2015 on my computer... I can pull it up later tonight if you don’t get an answer earlier

 

OK - on the 2015 EWD (I wouldn't expect 2018 to be much different except specifically concerning the added sensors for adaptive cruise, etc.):

Connector is J23


From the Engine Control and Transmission EWD:
Pin 1 is ground (white wire, black stripe)
Pin 4 is power from Engine Control Module (tan/brown wire)


From the Illumination and Taillight EWD:
Pin 2 is Illumination (-) (red wire), which eventually feeds back to the combination meter (gage cluster).
Pin 3 is Illumination (+) (green wire), which sources from the tail light relay and 7.5A "Panel" fuse

So near as I can tell, Pin 5 should be empty.

Full PDFs of each are attached if you want to dig deeper.

 

Why are you changing the switch? Putting in a supercharged switch?

 

Thanks Casey.

 

Supposed to be nice tomorrow, if I don't have a honey do list I will do it then.

 

I've searched to no avail. Is there a way to add tow/haul?
I have an sr which did not come with tow haul switch. Has anyone done this?
