I am on a VERY limited budget and I spent yesterday fitting a towbar to my P reg Kll in order to tow a tiny trailer of camping stuff. Tried to fit towbar electrics (as I have done on other cars in the past) but I cannot idenity the rear light wiring by tracing the iores to the bulbs as the wires go to the multiplugs on the rear light units. To avoid the coat of a Hyanes manul for a single job could anyone tell me the wire colours for the rear lights so I can finish the job!
