Back up light wiring?

Actually... I have a 65 Manual. I've glossed over the wiring diagrams a buncha times but it still doesn't give me the physical location of the light's wires. If I remember what I read correctly, the pushbutton style NSS only has one lead - for the NSS, and only later versions of the A904 have the 3 prong style (middle - NSS, left and right - reverse lights).

But yeah the reverse light switch on the 65's I've heard is on the column shifter unit itself.

The way I figure it is if I can find the wires going to and from the switch, perhaps I can reroute them to the late 3 prong switch? I don't know. I'm willing to try.

Worse comes to worse I wire up the B&M star shifter with the backup light switch kit. Then I guess it's just a matter of finding the backup light wires themselves?
