WR450f Rear Light Wiring Question

8 posts in this topic

Hi all,

While I am fairly adept mechanically, I readily admit that electric just isn't my thing.

I have a brand-new UFO rear fender for my '04, with the taillight under the fender like on later models. The challenge is that the wires on the new fender are bare...no way to plug into the female connector on the bike.

So my questions are...is there some way to easily pull the male connector off the OEM rear fender? Barring that, I may have to do some cutting. What size are these wires? And what would be a suitable replacement connector? I have an electric crimping pliers, but virually no knowledge in this area. Thoughts would be appreciated.

Thanks in advance.

This is what I have been doing today in the garage myself.

My thoughts are if you only want the tail light and arent wiring up a brake then keep the OE plug on the harness and splice the one from the tail lamp so you dont cut the harness. If you are doing a brake light addition and the third wire that comes along with that then go to radio shack and get part# 274 234 / 274 224 connectors so it will hook up.

Good luck and I share your dislike of electrical.

I built a complete headlight to taillight wiring harness using easternbeaver (for OEM connectors), corsa technic/snapon (for the proper ratcheting crimper tool/wire stripper), and steinair (for teflon wires). It was an expensive & very time consuming venture , but in the end the final product is MUCH better/durable than the OEM harness, plus now the bike has a full lighting kit to make it street legal. (it's posted in my thread towards around pg 3-6). I just couldn't believe that a 04 WR450 actually has pretty close to 450ft worth of wiring within the harness.

Thanks all. This was helpful, and I had not seen the easternbeaver link for the OEM connectors before.

For future reference, on my 2004 WR450f the blue wire is for the taillight and the black is ground. On the UFO fender, the white wire is for the taillight, the brown is ground, and the white and green wire is presumably for a brake light.
