I've yet to do this, and think it is really cool!  Like others have said, "factory should have done it".  I have no problem tearing into my bike as I have before. 

Couple of questions I have:  Is there any sequencing mod out there that uses the the trunk lights also?  I ride half the time with trunk. I would like to do the mod while incorporating the trunk lights also, or at least have them function as brake/turn signals also.

I have a new Kury 4710 here never used.

Anybody have sequencing tail/turn signals with your trunk lights functioning also????

Thanks,

Not having ever used the Kury 4710, I am not sure what it does. I can see by the data sheet I downloaded from the manufacturer's web site, it takes an input from the taillight. left signal, right signal, brake light, and ground. I can't discern what it produces.

What you have available after the sequencing signal mod is: at the trailer takeoff pigtail, Left Signal, Right Signal, Taillight, and Ground.

The signal taps originate from the LOWER bulb feed on the respective side. Meaning, anything hooked to it will flash with the LOWER bulb.

The sequencing mod routes the brake signal through the signal circuit. (just ans a standard trailer hookup does)

My assumption is that if the 4710 were hooked up without the brake feed wire, the trunk lights would operate exactly as the lower taillight bulb on the respective side. But then you would also have the same effect if the 4710 were eliminated and the trunk were wired in directly.

If the 4710 flashes the brake lights in the trunk, you would have to feed the brake input to get that effect. For this you would have to tap the white/pink wire GOING INTO pin B of the main-to-taillight harness connector.

My only concern with that approach would be a possible confusing look to the rear of the bike when the sequencing taillights "burst" and the trunk lights "burst" in a different manor. It may be worth a try, but picturing it, I think the trunk lights would be better sync'ed to the lower taillight.

 I hope this helps some, it's all I can offer. Hopefully, someone more schooled in the 4710 will chime in with some input.

Thank you both for the info. 

I think I will contact Gary @ www.vision-mod.com and see what he has to say.  I may end up buying his harness and selling my Kury 4710.  I just thought it would be neat to have the trunk lights work with the brakes lights, or turn signals, in conjuction with the sequencing taillight.

Since my trunk sits in the garage a lot, I guess it is a moot point.
