Wiring Harness Quick-Connect Adapter for Trailers

• This plug makes it easy to plug your trailer into your motorcycle wiring harness

• Forget splicing every time you want to pull your trailer

• Just place this special in-line plug at the point where your rear wiring harness connects to your main harness

• Then connect your trailer plug to the clearly-marked 5-wire pigtails, and you'll never have to do anything more than hitch up your trailer and plug it in

• You don't have to cut into the wiring harness of the motorcycle now or ever with this adapter

Customer Reviews

 haroldtibbs Posted:

Thank you j&p my trailer lights hooked up easy and working great

 dbkluna Posted:

Good idea; need to make sure you have the right plug ins for the right application, though, I had to send it back, did not fit and seemed kinda low quality for the price.

 ARThurpology Posted:

Not fit with the nightster

 tribe Posted:

works as advertised

 scrootertrash Posted:

Product arrived as promised and was exactly what I ordered.

 seesmith Posted:

This is a must, you don't have to hack up your bikes wiring harness to add a trailer

 S.V. Posted:

Just plain easy!

 mshalhoub1 Posted:

Works great.

 thos745 Posted:

I alwase very happy with JP products

 rdkolbe Posted:

Have not yet placed on my bike yet, but seems pretty solidly constructed. Seems to fit right into place..

 kcmoemt Posted:

Very easy to install. Worked great.

 bridgettej Posted:

Great piece, just the instructions are very vague. Once you figure it out is easy to install. Not sure if it was the harness or the trailer, but we blew out the accessory fuse and had to replace that, then everything worked great. So note to anyone, if you have headlight but nothing else, check the accessory fuse. That is a handy piece of information!!

 LtRussell Posted:

Very good product

 joedlc24 Posted:

It was exactly what i needed. Easy and clean.

 samchey Posted:

 Fallon Posted:

 kamperrv Posted:

we sell small cargo and campers for bike . these harnesses make it easy to hookup trailers to harleys. thanks , kamper korner

 moosh1200 Posted:

Worked like a charm. Intallation was a snap. My only complaint would be that the wires could have been longer.

 PHBall Posted:

Just plug in the part and hook up wires.

 mshalhoub1 Posted:

Easy to hook up.Wish it could have a quick disconnect on the outgoing end.

 cpwelder Posted:

Works great.

 moosh1200 Posted:

Product plugged right in, just as promised and worked perfectly. Only complaint is that the ends could have been a little longer.

 kpriebe Posted:

Just plug it in and wires are well marked

 ifican Posted:

Should have 5 ft. of wire and no splices to allow routing through the rear fender channel directly to the hitch connector. Also need instructions to remove security module to allow routing thru the channel.

 jeffdevitt Posted:

The wire harness worked well.I like soldered conections and heat shrink over crip for less chance of shorts and corrosion.thanks

 johnnieleesmith Posted:

This is my second one I bought. I have one on my Road King and now on my Ultra Classic. It is so easy to install and run my wireing harness with out having to make sure which wire is which. Its great (The Best)

 gw711 Posted:

Worked like a charm - just plug-in method made it easy to get the job done quickly.

 Shallico Posted:

delivery time was fast and the part was accurate to what was ordered.

 aghoward Posted:

This is a great product. It makes a breeze out of the job of installing a trailer light connection to a bike. Very easy to install.

 crazywolf01 Posted:

This part made my hooking up a trailer very easy and fun. Thanks

 SKing Posted:

This product was as easy to use as advertised. I just unplug it when I get where I'm going and put away in the trailer for safe keeping. No more messy wiring up under the fender or plug hanging down blowing in the breeze.

 Ohlson Posted:

Oustanding but pricey. It plugs right in rather than having to cut any wires. Can be taken on and off easily. The only reason I didn't give it 5 stars is the wires could be a tad longer to splice into the trailer harness.

Important Product Notes

Note: The Wiring Harness can also be used for hooking up lights for a side car and for installing any other lights that normally require cutting into the main harness of the motorcycle
