Reverse light cable

[unclealec]

I have been studying the Haynes manual wiring diagrams.

My brain hurts.

Could some guru with a better understanding of these things tell me what colour cable supplies power to the reverse lights on a 2013 Partner Tepee Outdoor?

It doesn't have a reverse warning bleeper system and while I am installing a towbar I want to fit an aftermarket reverse warning sensor device. I have the rear light clusters out and the trim panels off the rear inside quarters.

There should be numbers printed on the wire , Colours are sometimes random
The mulitplugs at the light clusters have or supposed to have, numbers on them . ie brake light is wire number 2100 in plug position 5 (r/h)

I think the wires you want are 2201 or 2202 at plug position 1,
Best check with a multimeter with ignition on and in reverse gear

Hey, thanks Brodfather111! Every day a schoolday!
I had actually noticed the printing on the cables but totally failed to realise their significance.
