Question Mix and Match Trailer & Hitch?

Will a Dauntless hitch's wiring connect properly (and without modification) to the Bushtec trailer's wiring? I'm not concerned about the physical connection - I know I'd have to get an adapter of some kind from Bushtec to put on the Dauntless hitch, to accept Bushtec's pin attachment thing.

Wink Re: Mix and Match Trailer & Hitch?

I have no idea about your question--but I just rode 30-45 miles behind Marc and Robin (names on the rear of their trailer). Red Goldwing, 2-up, pulling a trailer in 30 mph + cross winds on I-10 between Palm Springs and Blythe. You need whatever trailer/hitch they had. 80-90 mph and the trailer tracked like glue. Robin (assuming she was the pillion, not Marc) was also a fantastic pillion. I finally decided to pass them since (as we all know) the wind has less effect on you the faster you go.

Howard,

As long as you match the wires, left turn,right turn,stop,gnd/rtn it should not matter what hitch/trailer combination you have.

Re: Mix and Match Trailer & Hitch?

I was thinking more about the wiring connection (the plug itself) at the end of the Dauntless hitch wiring harness and the end of the Bushtec trailer wiring harness.

Re: Mix and Match Trailer & Hitch?

Howard,

You should be able to pickup an adapter at any Auto parts store that will go from a flat to the round one on the Dauntless, just count the number of pins. If you have difficulty finding one, chop off the one or the other and rewire to the type you like. If you have to change the connector, be sure to waterproof the one you replace.

Re: Mix and Match Trailer & Hitch?

I dug into the forum a little more and came up with this information regarding trailer wiring. Take a look, seems the LT 5 wire to Trailer 4 wire needs attention. http://www.bmwlt.com/forums/showthread.php?t=21731

Re: Mix and Match Trailer & Hitch?

I have the Dauntless 4 relay isolator with the Bushtec hitch combo,
just match the plugs (male/female) and you'll be fine.
I'll post the wiring diagram as soon as they fix the uploading issue.

here it is, first picture

Thanks guys.

Hans - 4-relay isolator? Dauntless includes a single relay with their hitch, according to their site. Now, I wouldn't know a relay isolator from a flux capacitor, but I just want to make sure I have the right things in hand when I get the hitch installed. I recall reading something very recently on this site about one- vs. four-relay isolators.

Re: Mix and Match Trailer & Hitch?

Yup they make a single relay and a four relay isolator,
my guess is the single is included and the four relay is additional $$,
the four relay has a relay for each function, tail light, brake light, left and right signal,
that way you're "covered" no matter where a short occurs,

cheap insurance in my opinion since anything electronic on the LT is mega$$$
the wiring harness itself is around $1200,
there was somebody right here on the forum that burned one up (right after he wired his trailer.)

if a wire rubbed through the insulation a short could occur if it touches ground like a frame etc.
I had an issue with my Bushtec where something in the "overfilled" trailer turned the dome light switch on,
it actually melted the maplight type ficture but fortunately never hurt the bike

Re: Mix and Match Trailer & Hitch?

The single relay is included as you suspected, Hans. I emailed Jay at DMC and he has changed my order to the four-relay - on a Saturday, no less. Continued prompt replies by these guys!

Thanks for the info.
