I have decided to try a headlight modulator again. So I picked a used unit up off e-bay. It looks to be a "universal"type as it has no specific connector on the ends. Tag says came off a 07 Nomad. I have been to manufactures site to see if I can find a wire diagram, but they only show newer models. Those wire colors are Red-hi beam power, White -hi beam out put, Blue low beam input, yellow low beam out put and black ground A green wire to flash system that connects to horn button. Mine has all these wires EXCEPT the white, that wire on my unit is gray. I am just assuming white on one unit = gray on mine.
Do you have to connect the low beam side of this unit to work? I was thinking just run the unit to high beam, thats all I had on last modulator.



SO if someone has installed one of these Signal Dynamics units and could point me in the right direction I would appreciate the help. I bought a H 11 headlight harness from O'reilly's and am wiring this unit to it so as to not hack up the OEM harness.

Pretty hard to make out anything on the printed sheet. The diagram best I can see is what I have gotten off their site. I worked on it today. I connected the blue and yellow in on low side, then the gray on mine I supose could call white and red on high. I got a modulation, but could not shut down high beam at all. Switch on handle bars had no effect. So I backed up and disconnected the low beam wires and only had high wires connected. All is good. Have high beam modulation and the handle bar control shuts the high beam on or off. I didnt mess with the green wire as I am just not convinced how I need to connect it.

Thanks Paul. Had it just like that except the green to horn. All lights stayed on no matter switch selection. Then it was just a matter of swapping wires to get what I wanted. So I guess I will just leave it alone. Best I can see, the connection of the low beam in this whole thing is just a switching function if you low beam ever died on you.
the headlight is already flashing, so if I connect the green "flash to warn" feature I dont understand what value I'm getting out of that. Unless it flashes the high if you had it off for some reason, say in a group on long distances o such.

On mine, it had two modulation speeds. If you hit the horn, it changes to the other speed for a little bit, then goes back to normal.

May have to try it out. So can I just connect to hot on horn? I have bad boy under fairing. I need to split the fairing in a few days as I am trying an antenna signal booster as mine seems to have poor reception.
