Trailer wiring to a GL1500 SE

[first-goldwing]

What is the best and easiest location I can splice in to the wiring harness to run wires to the existing receptacle. About 2 month ago I got this 1991 GL1200 SE and whoever had it before me never wired the plug. I have this 2015 Kompact/Kamp that I pulled with my old 1984 GL1200 and it worked great and was easy to wire in, this new one not so much. From what I have read https://www.kompactkamptrailers.com/sin ... ler-Wiring and understand I can do a direct wire because the lights on the trailer are all led. I have a 90 amp alternator that I just put on so I not to concerned about running the battery down.
Thanks for any help you can give me.

Probably rear brake/lights.

Do you have a five pin wiring diagram?

This is the easy way...

Easy plug and play above is a very good choice. While you don't need an isolator based on load, it doesn't hurt to have one and will ensure a trailer short does not affect bike fuses.

Most of the GL1500s I have seen were done by removing the cover under the trunk where the helmet hooks and trunk & door release latches are. Handful of Phillips (JIS) screws going up from the bottom. Then routing the wires behind the rear fender down to the hitch area.

I have one on my '93, highly recommended.... and no cutting/splicing either

Yes I do Thank you

An isolator is a really good idea but, if you do not want an isolator you can always go with a simple plug and play harness:

Another vote for the isolator. You just need to make sure it is not converting a 5 wire system down to a 4 wire. You trailer is a 5 wire system.

Also, get rid of the adapter you have that is going from the flat to round plug. Just put the round plug on the trailer and call it good. Just one less thing that can go wrong. If your wire harness on the trailer is not long enough, solder and heat shrink the connections. Then plastic loom or tape the wires up to the plug for a clean job.

Thanks that is what I will do.

Isolator or at least separate relays is the way. Isolator kit is good, you may have a few LEDS now, but you may someday want a different trailer.

Easiest way is a location where all your needed lighting wires are close together, like under trunk light (4 screws).

You'll need those 5 terminals.
Ground = White (do not count on hitch ball for a ground)
Right signal = Green
Left signal = Yellow
Brake = Red
Running or tail = Brown
