[TR] TR4 Reverse Lamp Switch

[Randall]

I could be mistaken, but I believe the reversing light was not standard on
TR4, at least not early ones.  They became required for the US market at
some point, but not until 1965 I believe (which would be TR4A).

The operating switch goes in the transmission top cover.  See illustration

(That's a TR6 illustration, but the location is the same.)

Should have a green wire supplying power, and a green/brown to the lamp.
Sorry, I can't help with routing or mounting.
