If you are looking to swap your base model steering wheel (without steering wheel controls) to a steering wheel with controls, this harness is likely needed.

This harness will get the missing LIN Bus circuit from the clock spring connector, tied back to the instrument cluster for control.

NOTE:  If you already performed the swap and lost your cruise control backlight illumination, it is reported by some customers, that adding this harness restores it.

NOTE:  This DOES require you to replace your base model cluster (with the manual control dial), to a compatible cluster that is controllable via the steering wheel.  Custom programming is needed. For more info and fitment, visit WAMS –

    This did the trick. Ordered my cluster from White Automotive & Media Services, my steering wheel from GM, and this harness. Absolutely delighted with the results. Got audio controls and all the steering wheel illumination and extra buttons work. DID NOT get a heated wheel. That requires a whole skill set I do not have. Took an hour to install.
