Connect 5 wire trailer to 4 wire bike.

[DanT]

The bike has 4 wire plug. White for Ground, a brown wire for tail/running lights. A yellow wire for left signal, green for rt signal also, when the brakes are on the yellow and green wire are hot. So, they serve as Brahe and signal wires.


the trailer has five wires. Blue for brake, yellow for right signal, brown for left signal, green for running lights, blue for ground.

what is the best way to connect the trailers five wires to the bikes four wire plug?

What do I do with the blue wire on the trailer?

I will assume the trailer turn signal lights are amber in color. If not let me know.

You have 2 basic options. Rewire the trailer and abandon the amber turn signal lights. Then split the left and right brake lights to 2 circuits so you can use them for combined turn/brake lights. The other option is to Wire in a converter like this.

You would likely have order it online because it is not as common as the other way.

Replace the BRP module/isolator with 5 wire out isolator. You should be able to glean what you need from my installation here: http://www.spyderlovers.com/forums/...us-other-lights-Part-1&highlight=trailer+wire

I wonder if there is any chance that whoever installed your trailer light harness installed a 5 to 4 converter under the Tupperware. If so, you couldn't remove it and bring the 5 wire out to the hitch. Just a thought.

That's what the BRP module is. Replacing that is my recommendation.
