How To Wire Turn Signals On A Motorcycle

Thanks so much kingfish and especially Cohberg for your help. It was Cohberg's diagram that ultimately got my project working. Thanks so much again for your time and attempt in creating the wiring diagram specific to my controller and of course for helping me identify what wires exercise what.

So that yous know your effort didn't become to waste, I wanted to show you that the project really did piece of work! And it's you I accept to thank for the success of this plow betoken project.

PARTS:
- handlebar controller (ebay, $8 or and then)
Yes, it'south truthful that the 1 I have is of poor quality. No dubiousness nearly that, merely it works.

- wires (ebay, $11 or and so)
Y'all tin become a diverseness of colors in a set rather than buying them individually. Dwelling house depot has wires too by the length.

- 3 pin flasher (ebay, $1.50 shipped)
As far as I know, they're all the aforementioned. Just get the cheapest one and await for it to arrive in the mail.

- butt connectors (Oreilly Auto Parts, $4)
The controller's wires aren't long enough and you'll need this to extend the wires the correct way.

- other type of connectors (True Value hardware, $3)
If y'all want any connections to be easily removable, get that blazon of connector. I don't know what it's called, but yous'll want the ones that volition connect the wires to the flasher hands.

- rut compress (True Value hardware, $3)
This is sort optional but is recommended for "waterproofing."

- electrical wire tape (garage, gratis)
I already had this laying around, but get a roll. It'southward worth it.

- license plate bolts (ebay, $8)
The bolts I described higher up are for auto license plates, simply I rotated the orientation to employ them every bit turn signals. Be certain to become the amber colored ones if you lot're using this blazon.

- wire management (Daiso japanese dollar fifty store, $1.50)
This but makes for a cleaner look. I don't like wires everywhere. Also protects it from the elements.

- quick splice connectors (True Value, $3)

TOOLS:
- wire stripper
- wire cutter
- wire crimper

It may assistance to run across how the end product looks like before starting on it yourself. Again, thank you so much Cohberg for creating the wiring diagram for me. I honestly wouldn't have been able to do information technology lonely. Much much appreciated. By the mode, I'll ship y'all a few bucks via Paypal as a donation for your effort if yous desire. Merely PM me your Paypal e-mail address.

STEP 0:
Unplug your ability source.

STEP 1:
Buy all the parts. I decided I wanted a make clean installation, and then I purchased a set of wires that are color coded to match the controller I bought. I'm new to all this and I didn't want to get confused past using all black wires and non knowing which i is which. The color coded wires help and for the price, information technology'due south decent. The wires coming out of the controller weren't long enough so I wanted the wire wire extension to be white, the light-green one to exist green, etc. Buying them in packs are pricey so I got some brusque lengths from ebay in a variety of colors.

STEP two:
Mountain your components, mainly the handlebar controller and the lights. Adapt the angle and location then that it's perfectly the manner you want information technology. Decide where you want to mount the flasher. Your wire lengths volition be determined by this and the proximity to the battery.

Step 3:
Identify the wires. Use Cohberg'due south wiring diagram! In the instance that you're using a different controller from the one I used above, utilise his method for identifying what wire does what. Pretty much just open up that puppy and encounter what color wire is leading to which switch. Pretty easy and helped me tremendously.

STEP 4:
Extend the controller wires to the proper length. The light-green, blue and white wires all needed to be lengthened to reach the battery. Mensurate and connect these wires to the wires coming out of the controller using a butt connector. Use heatshink besides if you want. How to use barrel connectors? Wait information technology up on Youtube, it'southward equally like shooting fish in a barrel as you lot think it is. Strip the terminate of the wire, put it into the butt connector pigsty, and crimp information technology.

Step 5:
If needed, extend the ruby and blackness turn signal wires to the battery area. My scoot's way short, so I didn't demand to extend it.

STEP 6:
Splice the white wire from the controller to the red wire on the left plough signal using a butt connector.

Step seven:
Splice the blue wire from the controller to the scarlet wire on the correct turn signal using a butt connector.

STEP eight:
Connect the green controller wire to the flasher. This simplifies things b/c now you only accept two more than pins on the flasher that need something to connect to.

Pace 9:
If you get nervous and don't want to splice your power wires just even so, you tin can try connecting the proper wires from the diagram temporarily to the bombardment just to see if the plough signal functions as intended. If information technology does, and so you can get alee and splice permanently

STEP 10:
This is where it gets complicated. Only follow Cohberg's diagram and it'll be fine. The reason information technology'southward tough is b/c our battery is not merely beingness used to operate the turn indicate. Chances are that you're using the battery to power your bike besides. This means a lot of splicing of wires.

There's simply a lot of wires to go on track of and to make it make clean looking is a scrap of an effort. Y'all should now still have i black wire coming out from each of the plow signals that aren't continued to anything. This part is complicated b/c both black wires from the plow signals demand to be continued to a single wire and the other end of that wire needs to split off again to splice into both the bombardment and the flasher. You'll spend most of your time on this footstep.

First just splice the 2 black wires from the turn signal to a single black wire. You can twist the two wires and only butt connect them into a new blackness wire to create a Y-shape.

STEP 11:
Splice the turn point ground wire from step above into the battery and into the flasher. You must however maintain the connection from the battery to the motor of your ebike/escoot. Then that means at that place's an extra splice that'due south not shown in the wiring diagram. Since my bombardment is more expensive than my motor, I decided to splice into the power wires on the motor rather than the power wires on my bombardment. This was besides a very conscious determination b/c I wanted my battery to be hands removed independent of this system so that I could use information technology on another ebike (which I plan to do often).

STEP 12:
Test information technology once again and hopefully information technology works and looks similar this:

THE ONLY HUMP:
The only hump I came across was that I got the negative and positive poles on the flasher reversed. Typically flashers are labeled on the tiptop side so that yous tin rotate it xc degrees to come across what pin does what. L is obvious since it's at the pinnacle, merely the E and B aren't so obvious for amateurs like myself. My flasher was labeled on the opposite side of where the pins are which is not the typical standard. I had accidentally mirrored the E and B pins. Once figuring out my error, I swapped it and bingo! It worked.
