Trailer wirering

Postby m2102 » Tue Jan 05, 2016 9:59 am



Question for those that did their own wirering for a trailer. I have a 2001 wing and plan to put a hitch on in the spring. The hitch is not a problem but installing the hook ups for plugging into trailer. Is their a pictorial that shows where to hook up and what and where did you get the parts to install. I have the trailer and it has a 4 flat plug on it, I know it will be s 5/4 hook up. Any and all help welcomed. Also not very wireing inclined so if possible pix would be great

The easiest (and best) way to do it is with a plug-and-play isolator, like this one:

You plug it into your bike according to its instructions, and then wire the ends to whatever trailer plug you have. Because it's an isolator, it has isolates your trailer wiring from your bike lighting wiring, so that if there is a short or fault in your trailer, it doesn't take out your bike lights (or wiring!).

Thanks WingAdmin fot the reply. I would guess i would use a 5/4 adapter to plug the trailer to at the hitch from the plug and play. Last quedtiom is, does it all go behind the licence plate plastic or under the top trunk where bag latches are?

I fit mine underneath the trunk top, it fits quite nicely in there. The 1800 is similar and it should fit fine there as well.

On my '02 1800 all the wires intercepted are behind and atop the rear fender panel between the saddlebags. Your PnP isolator and 5 to 4 wire converter will fit snugly under the trunk and atop the tire fender allowing the trailer hitch wire to be routed down the hitch bracket to the hitch ball area. You'll want to test everything before closing up the back of the bike, and if all is good you can reduce the excess wire length that may be pouring out of the isolator or converter (I had about 2 extra feet to stash or remove). I used 1/2" wire loom and heat shrink around the exposed hitch wire as it is susceptible road debris and wind wear. I also chose to upgrade my trailer lights to LED and wired a power-on only connection (with a relay) for my electric cooler adjacent the trailer light wires. I found if you have to chase wires forward its easiest to buy a few feet of hard plastic tubing and run that forward to the battery / fuse box area, it allows easy wire fishing and replacement plus adds some protection from wires shorting to ground.
