- Buick Ownership
- 2018 Opel Insignia TourX ;)
Opel steering wheel will be a tough sell since only one person claimed that he was able to successfully retrofit Regal without showing any detailed photographic evidence. Buick's steering wheel has different connectors, harnesses, and slightly different functions I doubt that it can be easily transplanted.
The above started as I have already committed to buying both a standard Opel steering wheel and a GSi/OPC version for my conversion.
As I was told quite the opposite..
But there could be caveats..
So I have dug a bit deeper..
US harness for ALL 2018-2020 Regals
This fits ALL 2018 - 2020 Regals ( with Heated wheel )
Standard Opel Wheel has same plugs and thus would seem same harness as well
Now from all my comparisons.. I have done..
The pin outs look the same.. for the controls and the airbag. Even the Airbag connector.
Confirmed 39136242 the part number of the clock spring is the same.
The ONLY difference is the same as if you swap a Heated wheel with a non-Heated wheel. You need the wires for the heated part..
It DOES seem if the Flat bottom one with the paddles does have an extra connector and doubtful the paddles would work with the harness, but would be there for looks. The Standard wheel though does seem to not be a problem.
Also the button for the Heated Steering wheel seems to change location, to the "dead" button in the center our left D pad.. and in Europe they include a button for what looks to be a speed limiter ? Maybe the ACC can drop your cars speed to match the limit ?
GSi/OPC Wheel with paddles
Standard Opel Wheel
Otherwise most all the controls are in the same place.. the exception is the paddles which simply will be there for show and forementioned heated wheel and speed limiter.
Otherwise its' simply a different look and size for the buttons.
This all said, I know from previous wiring projects with Opels over the years..
Bosch/Opel/Germany ( Not written in stone.. but what I have seen over the years )
BLACK = Battery (+) ( Also sometimes ground )
Brown = Switched (+)
White = ECU Controlled (+)
Green = ( -5v, coil and/or ignition )
Vs the GM
Red = Battery (+) ( Sometimes switched )
Yellow = Switched (+)
Orange = Accessory (+)
Black = 12V Ground
Brown = ECU Ground
Pink = Coil/Ignition
etc... etc.. so the color things maybe German standard vs GM NA standard so techs don't get confused.
I have all the pictures and will be back in a few with the results.
