I have a '97 Toyota 4Runner (with factory towing package) that I have been using to tow my Montauk. The 4Runner has separate turn and brake lights. I noticed that on the trailer both brake lights flash when I apply the signal either right or left. I purchased the additional wiring kit from Boater's World and just glanced at the instructions to wiring. Is this an easy project. Anyone have a 4Runner or comparable vehicle that needed the same adapter.

You need an adapter that changes it back to a single light(foreign to domestic)available at Walmart or any trailer supply store. About $10-15

It is hard to deduce exactly how you have it wired now. The basic problem is that on domestic cars and trailers, at the rear of the car the same lamp is used for both brake light and turn signal indication.

On your foreign vehicle, you evidently have separate lamps for turn signals (yellow lens) and brake light (red lens) functions.

Your vehicle has circuits for
--running lights
--brake lights
--right turn light
--left turn light

Your trailer is wired for
--running lights
--right turn/brake light
--left turn/brake light

You need to convert from four circuits to three. This is done with a few ten cent diodes. Often you can get a pre-made device that may even just plug into your existing vehicle wiring harness.

Here is a chart that explains the color codes typically seen:

Here is another chart showing color codes of common trailer wiring. This is handier than the other since it is in black and white and can be printed on a non-color printer and still retain it information content.
