Expert Reply:

A co-worker and I cobbled something together a few years ago that we called the Frankenadapter. It would consist of the # 118158 Vehicle to Vehicle Taillight Converter, a 4-pole trailer-side connector like # HM38168 and a 5 pin round vehicle side connector like # PK11502. The adapter would be constructed as shown in the provided photo. The 5 pin connector would connect to the wires shown to the right.

The adapter will separate the stop lamp signal from the right and left turn signals so your motorcycle trailer can be towed with separate brake lamps.
