You'll need a new ABS module. Also need a new IMPA camera/module.
The parts you need should match the list I provided since @NMMI82 and I both have 502a with factory LKA.

If you have a non 502a Lariat I think you should verify the correct wires are present at the bumper for the CCM (radar module) harness. It's been a while, I don't recall if that is XLT to Lariat or within Lariat trims.

I have LED's so I'm assuming the wiring harness would need to be changed to have the CCM module connector. My camera is JL3T-19H406-AG. No idea about the ABS module.

So far, I still think my instructions / parts list are what you need.
