This is my second review on this item, as I just had to replace this unit. Installed the original unit in Jan 2007. Device "died" after 21 months service. Would expect more out of a solid state unit. No shorts or blown fuses. It just failed. Fortunately, splicing or tearing into the rear harness area again was not necessary, as I confirmed continuity of the original wiring/connections (soldered) from the device output to the lights - all checked good. Then, I confirmed that I had brake light power going into the unit, but way too low voltage coming out of the unit on any of the wires from the device, hence, clearly, the device was not functioning. Since I mounted the original unit under the seat on the right side frame rail (nice vertical flat area to sick it to there), I removed the unit from where it was stuck to the frame, and cut the wires coming off of the old unit (close to the unit), and discarged the old unit. Also, rather than "splice" the wires from the new modulator onto the "cut wires" from the older unit, I installed a Female LP4 (4Pin) power connector (Radio Shack) to bike side wiring (the wires I just cut) and a male LP4 connector on the new modulator wires, for a "plug and play" connection should I ever have to replace it again, now that I know that is a possibility! I still love what the unit does!

This was a bit more challenging to install but worth every minute. Works great.

I'll echo the previous mentioning of poor customer service and no GL instructions. This piece is really slick when used with the Big Bike trunk LEDS. Decent install instruction can be found in this thread. http://www.gl1800riders.com/forums/viewtopic.php?t=89697&highlight=wig+wag

Great product. Crappy instructions.

The other reviewers are correct. Can they not write a one page set of instructions?

What good is a great product that you can't install?

There are installation instruction on the web for these. Insallation isn't hard, but does require some patience, a volt meter, and a soldering iron.

Perhaps some Wing rider should write directions for them?

Excellent product for safety. Priced right... HOWEVER, this company does not have a clue how to install their product on a Gold Wing. NOR do they care. VERY VERY POOR CUSTOMER SERVICE. THEY COULD NOT CARE LESS. Their awful directions are useless. I believe you can now find help from the message boards and I do highly recommend installing one. But This Company Needs to get the message to actually WRITE instructions for the Wingers!!

Now for the real world lesson. Someone should knock this thing off and put these people out of business. I'm so disappointed we all continue to hand them our $$ and they can't even write a simple one-page set of installation instructions.

Bottom Line: buy one, get some friend or on-line help to install and you will be safer. Don't be naive to think - regardless of how handy you are - you can simply get the box and plug and play. It is a half a day translating their diagram and how that might apply to your GW. Geez.....

Surely Kisan or Electrical Connection can make one of these AND some instructions for Wingers.
