Expert Reply:
Typically the wire colors you mentioned indicate yellow for reverse light, green for running light, blue for brake controller output, brown for right turn/stop, black for 12 volt accessory circuit, and red for left turn stop if this is a 7-way wired for an RV. Only wire color you didn't mention though is white which is usually for ground. I attached a 7-way diagram for more info as well.
Other option is to use a jumper wire from a 12 volt battery's positive post to apply voltage to each wire to see which circuit activates and wire accordingly.
