2015 GL1800 Trailer wiring

[Rogerw]

Anyone know what the color codes are
Blue, green, yellow, Brown
what are the goldwing colors for 2015 that are equal to these colors?

I am afraid the bike is so new there are no manuals out to the public yet. Might try calling the dealer you bought it from see if they can give you the bike wire color codes. The other I do not know, I just use an ohm meter and trace them.

I did some more checking and I have the 2010 schematic, which I sent in the first post. However, I checked my 2013 manual and the wiring is the same coloring. So the best I can get you up to is the 2013. But it may be the same. Use volt meter and check each wire to be sure of the function. Good Luck!

Forgot to include the schematic. Wife interrupted me with questions........Geeez.

Thanks, I will check with your diagram also with a volt meter.

I found this on line and think it may give you a hand up on the trailer color codes. Take care!


Trailer Wiring Connectors

Various connectors are available from four to seven pins that allow for the transfer of power for the lighting as well as auxiliary functions such as an electric trailer brake controller, backup lights, or a 12V power supply for a winch or interior trailer lights. Choose a connector that has the required number of pins for the functions required for your trailer. If the connector is under the vehicle, you will want to use a mounting bracket to attach it to the vehicle. This will help prevent damage that may occur if the connector is left dangling.

4 Way & 5 Way 6 Way & 7 Way
7 Way 6 Way 5 Way 4 Way Right Turn Green 18 16 Right turn of vehicle's wiring harness Trailer's right turn signal
Left Turn Yellow 18 16 Left turn of vehicle's wiring harness Trailer's left turn signal

Back Up Purple 16 Back up circuit of vehicle's wiring harness Back up lights (if available) / Hydraulic coupler.
This chart is a typical guide, wire colors may vary based on manufacturers. Use a circuit tester to verify connections.


4-Way Connectors

4-Way connectors are available allowing the basic hookup of the three lighting functions (running, turn, and brake lights) plus one pin is provided for a ground wire. Most standard light duty trailers will use a 4-pole flat connector.

Best thing to do is use a trailer isolator, which protects your delicate (and expensive) Goldwing lighting wiring from inadvertent short circuits in the trailer, and deals with all the connections for you, so you don't have to match wire colors.

I am with WingAdmin on this. Your wing is a 5 wire system and if you are going to a 4 wire, you will need a converter along with the isolator. The turn signal and brake lights are on a separate wire and not combined like a 4 wire system. The one he listed is plug and play on the bike. I used the one from Electrical Connection, but does the same thing as the one he listed.
