    Default Bike has 5 wire trailer plug and trailer has 4 wire plug -- Adapter???

    Guys,

    Is there an adapter that converts the 5 wire plug on the bike to the 4 wire on the trailer.
    If so where can I buy one?

    thanks,
    Hwilks

    You may want to add one of these too in order to maintain isolation from the rest of the bike's electronics...

    The 5th wire is a brake circuit and is most likely unused. Clip it.

    This is not true. On your goldwing you have seperate wires for each turn signal, running lights, ground and the extra wire is for your brake lights. Do not clip it or you won't have brake lights on your trailer. If your trailer has one wire for turn signals and brake lights (4 way) then you will need an adaptor. If you have seperate turn signals from your brake lights (5 wire) just get a 5 wire plug.

    Default Same but different

    Sorry to tag on to the OP's question, but this seemed like a logical time to ask. Is there a plug that will do the same conversion in reverse, i.e. a 4 pin flaT plug on the bike to a 5 pin on the trailer?

    Maybe I do not understand the question but I do not think there is an adapter that will turn a five wire plug into a four wire plug. I think you will have to change the plug/wiring on one or the other.

    Either a five wire on the trailer or get the converter and wire up a four wire on the bike.

    But as I said I may not understand the question you are asking...

    No sir, you will have to re-wire the trailer to match the bike. If the trailer is 5 wires you probably have independent (amber) turn signals and separate (red) brake and turn.

    I just went through this with my Nissan Pathfinder, 5 wires out to a 4 pin connector on the trailer. I got an adapter from the local U-Haul trailer rental place for $17.99. Product number 14486. The red wire from the car/bike is the brake light circuit. Hope you have a U-Haul nearby. Cliff. http://www.uhaul.com/MovingSupplies/...-Flat?id=13684

    Default converters

    You can get converters to go either way, absolutely. A isolater is a very good idea on the motorcycle, get it. Park nose out for safety. A five wire has the brake seperate from the turn signals. On cars and trucks the turn signals do a combination in the turn signal switch, or multifunction switch as they call it today.
    Go by function not wire color

    As stated, bikes have five wires... one brake, one for each turn signal, one for tail light, one ground. Five total, unlike cars that have brake lights double as turn signals and just need four. Best be informed before advising people..... there are several companies that make a "5 to 4" converter for those who have a trailer wired the standard way.

    The problem of throwing on some type of adapter and riding off is that without installing an isolator, the bikes wiring is taking the entire load of the trailer's lights. Depending on what you have added to the bike already and the number of lights on the trailer, it my just be too much
