Reverse lights

Hi all, after replacing my tail lights, I have realised that I have not had reverse lights on my old lights or my new ones. I think I have located the reason for this by crawling under the car and finding a switch that appears to be on the bellhousing area, that has bare terminals and no wires going to it.
My trouble is that I cannot see what would plug into it. Further back in the loom there is a two pin connector that has 12v to it, so is there a small 30cm loom that connects the two?
I should mention that my D21 is a 96 model with a Teranno non intercooled turbo diesel engine and probably a Teranno gearbox as well, is there is any difference?
I need to test to see if the plug I have found is actually for the reverse lights, most likely by bridging the terminals, I will either blow a fuse or my reverse lights will come on!
Does anyone know if I am on the right track?
Anyone else had a similar problem?

Well it's been a productive day, I bridged the two pins and the reverse lights lit up, now I just need to make a loom to join them to the switch.
Problem solved it seems, provided the switch works.

Good work. 5 hours and you sorted the problem.
They're the problems that you want..., the easy to find and fix ones.

Rarely do problems get sorted that easily, between that and my indicators flashing too fast, I feel like I have had a bit of a win.

Yeah buddy even the little victories have to count for something
