Like I said above, with CAN buses and multiplexing, not every switch has its own wires running back to the computer. I'd bet the Insignia cluster has the exact same number of wires and same plug as ours, but the difference would be we have a dummy/blank switch for start/stop disable whereas their cluster adds the electronics to talk on the CAN bus.Pull the plate up and see if there is wiring there...
Is that switch ahead of the gearshift along with the start/stop disable, or in a different location altogether? If in a different location, it might make sense to eliminate an entire harness leg that will never be used.There is no wiring for the rear fog lamp like the Euro cars have. The housings themselves are also different. (I’ve verified in person.)
