Adding Lane assist to a 502A

Ok, so all I saw was the green arrows in the IPC. There was no vibration in the steering wheel and no aid in coming back to my lane.
However, this may be because I didn't calibrate it properly. I am going to run that again this afternoon and report back. It never went yellow when drifting.

It's the main cab harness that does not have the wiring you need to install LKA.
Strange thing is the pin at C3133 is populated. I'll have to figure out where that goes. I believe that will be the reverse sense signal that the BCM uses in the regular autodimm mirror. That there is airbags every-freakin-where I need to work doesn't give me a warm and fuzzy either.
So at this point, it's not a simple swapping harnesses and changing programming if you want LKA in one that didn't come with it oem.
Doable, but you're going to have to get in there and do some work if you want it to look oem. The alternative is to put a switch up in the mirror somewhere and use that to ground the mirror pin 9 to turn LKA on and off.

C3133 location, bottom of console
C314 location rear of cab
Hopefully these Help! It should be "Easy" to run a wire from the Rear of the cab C314, Pin 9, along the floor and to the switch harness location C3133 if you have the console out to put in the harness...
Ok, not exactly Easy, but very Doable.
This is also coming from a guy that has never added a Pin, Repinned anything, and I only THINK I understand these wiring diagrams.

These diagrams are great. Do you have one that shows how the factory routes the wires for auxiliary fuse box under the hood for the upfitter switches? Part# HC3Z-14A303-F, and I believe the harness part# is HC3Z-15A404-A.
Thanks

Awesome diagrams Vinnie. I think knowing what I know now, I would just run a wire from Pin 9 under the front of the headliner and down the A pillar, behind the dash, and to the center console to get the OEM switch working.

Aux Fuse box/upfitter switches would be for Raptor. The Manual I have is specific to the 2016 and the Lariat. It wouldn't have that.

Ok, Livinitup, maybe you can chime in here and assist. I have the system active and calibrated. It goes away when you start calibration and it pops back up when it is calibrated just like you said. It is reading the lanes fine and when I change the intensity settings the steering while vibrates as an example of the setting. However, I cannot seem to make it actually vibrate when drifting or bring you back into the lane.
Is there any audible alarm?
How forceful does it bring you back and how far do you have to drift?
Do you think there is another Forscan setting we need to enable?
Also, I never see the lines go yellow. They are either green or off.
Thanks in advance.
