Mogs already have glitchy electrics as seen by the many query threads on here
So why add further connections, wiring & a vanity switch ?
I agree Jon. In the case of our cars though all the complexity for start button is already there including its connector, like it or not. Ironically if you don't take up and pay for the start button option a jumper has to be added to this connector to enable key start.
MMC not wanting to miss a trick I guess
