no trailer brake lights

Post by hap2 » Sun Jul 19, 2015 7:21 pm



With my car hooked up to the trailer, all lights on the trailer (including brake lights) work.

With the bike hooked up to the trailer, the brake lights work on the bike. but not on the trailer. There is no power going to the brake light wire on the bike hitch. So, I need help to figure out:
Where the switch is that activates power going to the hitch plug when I apply the brakes? (front or rear, it doesn't matter) And how exactly do I get at that switch?

OR is there a wire going from the tail lights on the bike to the hitch plug (& what color wud it b?)

Does the trailer have separate brake/run and signal lights, (5 wire system) or all in one? (4 wire system)

If it's the latter, then you'll need a 5 to 4 wire converter, in order for your trailer lights to function properly with your bike!

Trailer has a 4 flat plug, so I assume all-in-one.

That is the issue, you will need a 5 wire ( ground, run, stop, l turn, r turn ) to 4 wire ( ground, run stop/l turn, stop/ r turn ) converter box. You can get them most any place auto parts are sold, even Walmart and KMart carry them in most stores

I'm wondering why the 1500's have a 5 way wiring system for trailers compared to just a regular car? What's the advantage?

I don't know if it's an advantage or not. But the reason you need it is because your bike has separate turn signals from brake/running lights. On a lot of cars, there is only one bulb for all functions. Meaning your car most likely does not have amber turn signals.

1500's don't have ANY wiring system for trailers. All trailer wiring on Goldwings is added as an aftermarket product like this:

So the type of wiring is entirely dependent on the type of harness installed.

Find your nearest U-Haul Center (not Dealer, Center). They 5-to-4 adapters at a reasonable price.

You can buy those adapters pretty much anywhere - even Walmart carries them.
