+2 Dash - whats this Switch for?

[hastu]

Still assembling my +2 S130 i found Switches under the Dash. 2 Switches ssems to be for Drive and Fog Light. But in the upper right there is a Push Switch (blue Circle) that i have no idea what it is for.
In the Harness seems to be 2 Wires (white-Green and purple-red) for this Switch.
Any ideas what this Switch is for? Seems to be Original

Don’t think it’s original…

The colours are (in the Lucas scheme) as follows

White / Green : fuel pump #2
Purple / Red : Switches to map light, under bonnet light, glove box light and boot lamp when fed direct from battery fuse

According to https://www.mgexp.com/article/lucas-wir ... r-guide.50

I don’t think we can trust that. It’s likely to be a fan or fuel pump override, but trace the loom to be sure.

There is a switch in that position on my +2S. Its to test the brake fail light. Gary

No...I certainly haven't got that switch on my +2S130. I tend to agree with JonB I don't think that is original.

I run a 1971 Plus 2S and think you might be holding a button that when pushed zeros out the trip odometer.
