I got it figured out by finding a simple breakdown on some Harley forum about how to wire 2 to 3 wire turn signal so I figured I’d post it here just in case someone else will be searching for this and comes across it. Universal turn signals will likely come with two wires, especially if they’re the LED ones, some have 3 but those are harder to find.
Simple break down
Turn signal
- negative wire: probably black
- positive wire: red, yellow, or whatever other color
WR250X/R
- negative wire: black
- directional or intermittent: green on right, brown on left
- constant power: blue
Connect on each side negative from turn signal to negative on WR (black to black). Connect the other turn signal wire to brown or green wire, depending on which side you’re wiring. Tie the blue wire off. Don’t cross the wires or turn the bike on or some fuses will be blown. Turn signals lose the constant on now which means it’s possibly not street legal but I don’t think any cop will give a hard time about that. There is a way to do it but I’ve yet to learn it, once I do, I’ll probab set it up right. I bought some $6 turn signals off eBay because I was sick of how ugly the stock ones looked. They look and function great. The turn signal itself is very bright when flashing. Overall I think well worth it. If I knew what I was doing from the get go, I’d say this maybe takes half hour to do.
