Caddy 2017 Highline module under the steering wheel
Posted: Mon Mar 09, 2026 10:09 pm
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?
