OK, bought a new headlight off ebay, good price( I hope), actually looks nice, chrome.

The problem, the original Harley headlight has 3 wires going to the harness, black, yellow andwhite.
The new light only has 2 wires, white and blue.

I can do almost any fabricating and normal high voltage stuff, but when it comes to low voltage electrical, lets just say, I've seen smoke in the past, not into frying my new bike.

Normally I would assume one of the 3 on the original is a ground, (or maybe a hifh beam line?) but hey, thougth I'd ask someone who knows for sure.

Figured I'd get this done while I have my tank off doing other things, thanks

 

My Dyna service manual shows the white and yellow as high and low beam (not sure which is which). The black is ground. I can't help with the new one. Maybe it grounds through the chassis.

 

The color coding is in your service manual. I believe yellow is high, white low and you remove the black from your stock plug since its ground. The new headlight is grounded through the mounting. I just installed a new one from Eastern Performanceon my bike. Looks good, works fine.

 

Thanks Capt,

Just got done sifting through past threads, actually only mentioned that black was ground.
I'm guessing I'll just cap off the black, and see where the other two leave me when connected.
Also as in other threads, if I get them backwards, the worse that can happen is my high / low will be backwards. I can always switch them back the next time I'm in the harness.

Thanks for your help, will do this in the morning, gotta take the wife out tonight.
