Here's where the BackOff comes in. This unit is 3 1/2" x 1 1/2" x 1/2" (inches) in size. Lucky for me it has only two wires sticking out of it -- a red one and a white one. Being different colors, I figure they have to be hooked in two different places. So, I take the saddle off the bike and find the brake wire leading back from the rear fender (not too difficult).

This wire is connected to (I think) the positive lead (blue/red wire) from the battery (probably switched with the key and brake switch, and fused - editor) with a bullet connector. I disconnect the bullet connector in the brake wire, install a bullet connector on the red BackOff lead and make a connection. I install a female bullet connector to the white lead from the BO and insert the (fender) lead from the brake light (I don't recall there being a lead from each bulb, but if there was, I simply spliced them into a single male bullet connector).

In the meantime, my rear signals are connected in the usual fashion, except like I said, I got this extra wire hanging loose. So, not wanting this extra wire to go to waste, I add a little more wire to it and splice it in to the white lead of the BackOff. Then for extra good measure I splice another wire into the white BackOff lead and run it up to an LED brake light I had added to the sissybar (the LED is grounded on the sissy bar.)

As currently configured, when I hit the binders, the regular brake light, the LED light and one filament of each bulb of the rear signals light up (what was your first clue that I was hit from behind?) If I'm signaling a turn while braking, the other filament of one signal light is operating also. Note: the BackOff does not produce a continuous blinking effect---it's pulse is one long, three short. Therefore, a driver will be able to observe the difference in the blinking signal lights and will know you're turning---or, if he's looking, at least he'll know something's up and he better back the fuck off (that's what I would have named it). Just to reduce the possiblity of any confusion, if I'm gonna brake to make a turn, I signal well in advance of braking (I usually use my engine to slow down, so this really isn't a big problem).

As for mounting the little bugger, I'm not one of those guys that has to have everything perfect. As I recall, the thing comes with two-sided sticky tape, and the dimensions I gave you include the little mounting ears (for screw-in applications), one on each end--boy those guys were thinkin ahead, weren't they?) I just tucked the thing in loose under the seat--it has worked fine so far (2 years).

For parts and tools, ya only need some wire if you're gonna connect additional lighting. Otherwise, a crimping tool and male and female bullet connectors are about all ya need (the stock bullet connectors on the bike are SMALL, so just because ya have big fingers, don't go for the magnums from the hardware store.)

Expertise Required:	Minimal (I'm living proof of that!)
Time:	How smart are ya? In my case, maybe an hour, counting the time required to down several cool ones.

I love this gizmo. When I'm at a stop light, I keep the brake on. I figure a set of flashing lights gives me a little extra chance of alerting a distracted or daydreaming driver before she plows into me -- probably about 3 seconds in the case of your average ditsy female cager. It's my way of getting revenge -- I want her to scream in total panic just before she nails me.
