The Hop-Up: You may be saying to yourself, “that’s a chick bike,” and you’re right. But honestly, it’s so much more than that. It’s one badass bike. http://www.quadmagazine.com/quad/features/article/0,24942,1587044,00.html
Found this system and have tried it on my quad (and bikes) had to mod the mount a little to fit my wider bars but that was simple with some aluminum flat stock adding 2" to each side. Simple wiring and all in one unit so did not have to bury an amp....loaded it up with music and also use my bluetooth on phone...wanted to share....its on ebay under firehousetechnology . wanted to share will post more as I ride more but so far so good and simple addition! They are on facebook also under firehouse technology if you wanted to see what they posted
Here is video link to there initial post and video
This is a 2008 Polaris Sportsman 500 X2 modification to make the taillights only come on when the headlights are on. Normally the taillights are always on, which I admit is very helpful when following someone on the trail in lowlight conditions. I prefer to have the option of when the lights are on, so I installed the following mod to my Polaris.
- 1 x Bosch style relay. Amazon: AGT (5 Pack) 30/40 AMP Relay with Harness; spdt 12V Bosch Style (40AMP-HRNS) for 13.99.
- 1 x 1N400X diode (I used a 1N4004, but any diode in the series should be fine)
- Wire connectors, preferably marine grade heat shrinkable.
- Heat shrink wrap.
- Wire protection: split loom and nylon sleeve.
- Wire: 5 feet of 16-18 gauge.
Bosch relay info: CHETS CIRCUITS (and scroll down to yellow diagram near mid page--thanks Chet)
1. Splice into a headlamp wire and run it to relay pin 85; ground pin 86 to the frame.
2. Cut the two taillight wires (L and R), and connect one side of the cut (both L and R) to relay pin 30, and the other side to pin 87.
3. When the headlights are on, power from the headlight wire to pin 85 causes the relay to close the taillight connection through pins 30 and 87 to make the taillights turn on. When the headlights are off, the connection between pins 30 and 87 is open, resulting in the taillights being off.
4. The brake lights are on their own circuit, so will still work normally.
5. The relay only draws about 170 milliamps from the headlight splice so there is no apparent change in headlight intensity.
6. I don’t think joining the individual L and R taillight wires to pass through the relay (pins 30 and 87) has any effect on the electrical system since they come from the same splice upstream.
My install used a 5 pin relay with pig tail wire connector. I removed the unneeded center pin wire (87a pin):
I pulled out the 85 and 86 wire pins and soldered a 1N4004 diode in as a precaution against back EMF. Back EMF is a voltage spike caused when power is removed from the relay that could cause damage to switches in a system not specifically designed to have a relay. An electrician may know better whether or not this is needed to protect the headlight system of the quad. Note the diode’s cathode end must connect to the power wire (pin 85 in this case), and anode end must connect to the grounded wire (pin 86), I.E. Reversing the diode polarity will cause a short and potential damage. An option is to purchase a relay with an integrated diode. Diodes are cheap at Radio Shack. I suspect installing a diode is overkill, but I had the time and energy . . .
Soldered in diode and with connectors and diode reinstalled:
Next, I found a place to mount the relay. On the left side frame, next to the air box, was a foot-well brace bar that bolts into the frame. I mounted the relay on this bolt and also connected the relay ground wire (pin 86) to the bolt by crimping a ring connector to the wire:
Then I very carefully removed a half inch of insulation from the front left headlight power wire (a green wire on my quad) and soldered in a wire to connect to pin 85. I put a nylon sleeve on this wire and ran it back to the relay, following existing wire looms and zip tying it in place:
Next I accessed the taillight wires--the PS500 X2 made this easy since it has a dump bed that lifts up. For typical quads, you may need to remove the rear storage rack to access the taillight loom. As you can see in the pic, my taillight wires are red w/white trace, the brake light wires are orange, and the ground wires are dark brown. Cut the taillight wires and crimp on connectors, then connect to pins 30 and 87 (black and blue wires in my case). Polarity doesn’t matter. View from above:
Made all the connections to the relay then tested the light system. Worked like a champ. I used shrink wrap and tape to seal the connections then put split loom wire protection over the wires between the relay and taillight loom and zip tied everything in place.
I also spliced in a license plate light to the taillight circuit. I used tape to mask the dome so only a slit is open to shine softly on the plate.
Had a couple more pics, but apparently can only upload up to 5 total, or per post.
