Caddy 2017 Highline module under the steering wheel

[R3Z0R]

I have a 2017 Caddy 75 kW with a Highline module under the steering wheel.

I installed a multifunction steering wheel and replaced the airbag wiring, but now the horn doesn’t work — the horn pins are wired differently.



Has anyone installed a multifunction wheel for controlling the onboard computer, volume, and cruise control? What needs to be done to make it fully functional? Any guides or tips from someone who’s done it?
