I have a 12-pin flat plug on my vehicle for use with the caravan. I have bought a mac raclight so I can illuminate the numberplate when carrying my bike.
I need to wire the "mac raclight" to a 7-pin flat plug so I can use it with the fitting on my vehicle. Problem is that the mac raclight only has three wires which are red, yellow and white which do not coincide with the colours on the Repco plug -ie, the yellow on the Repco plug is for a turning light which I do not have on the mac raclight. Being a bit of a dunce I do not know what these colours represent and am not sure which hole to put them in on the new Repco 7pin plug. Can anybody please give me a bit of information. (The mac raclight only has a light to illuminate the numberplate and a stop-light).

at a guess, I would say white is earth, red is stop, that leaves yellow for plate light.

S----- stop light -----E----- plate light -----P
Measure the resistances between each pair of wires (S & E, E & P, S & P). The pair with the largest resistance will be S & P. The remaining wire will then be Earth.
Now remove one of the bulbs and measure the resistances between S & E and E & P. This will identify each bulb.
If the lamps are LEDs rather than incandescents, then remove both lamps and measure the resistances between each of the lamp's terminals and each of the wires. The wire that is common to both lamps is the Earth.

The white wire is earth, the red are the tail lights and the yellow is the
brake light. Please feel free the call the number below for further
assistants.
BTW, even though the response to my support question was commendably prompt, I don't know how I should feel about a company that spells its own address as "Evetron Hills" instead of "Everton Hills", nor am I too sure about how many "further assistants" they might have.

Close enough isn't always good enough, especially in electrical situations.
I prefer to get my information from credible, authoritative sources. The Internet has too much noise and very little signal.

G'day Dorian
you are quite correct, you did the research and produced the correct answer
I was guessing and I shouldn't have done that.
my apologies to the OP for my lax attitude.

Might have helped if they had used standard colours for their macrac light too. But then again, there is no law that says they should (except common sense).

Brown is licence and rear lamps I think.

BTW, it would have helped a lot if the OP had correctly described the product as a "mac rac light" or "mac*rac light".
www.macrac.com.au/products/accessories/other-accessories/
Google doesn't find too many "raclights".
Here is the company's contact page:
