i assume the green/white wire from the headlight and the green/white wire from the high beam get connected together and those get grounded?? is that correct? if so where do most people ground these to? one of the bolts that hold the headlight bucket on ? on the inside of the bucket? or is there a better way? i dont weld....

yes kirbby.. have all parts.. power goes in the dimmer switch then the blue and white go to the headlight.. ( all done ) - blue headlight wire goes in the double, white goes to wite,,, then the blue from the high beam indicator goes in the double plug also.. now left with green from headlight and green from high beam indicator.. just need to know if those to get linked together then grounded....if so.... what is best way and place to ground them..

Ya you need that short ground wire to be "correct" but you only need to ground the green wire from the high beam indicator light to make it work. You really need for someone to pull their headlight out of the bucket and take some pics for you. I have one Z at home that's buried at the moment. I might bring one home from storage tomorrow. One way or another I'll get some pics for you. I can tell you tho...if you put all of the correct wires into the bucket, it's pretty self explanatory. You might have a non-non-"correct" wire pigtail/bulb socket in your pic. I think it should have a female duplex on one of those wires.

This should be everything in your hl bucket. The wire colors on this dimmer switch do not match what the wire diagram says, but they work like this.

Br/red to harness br/red.

White to hl br/white.

Blue to hl blue

Thats like mine.I did not want to post a picture because when I took mine apart I saw that ground wire in the second picture had the ring terminal that is on the screw on the light assembly replaced by me at some time. Was not sure that it originally went to that screw. But thats it.

ya guys.. the only reason i asked was because my pigtail from light also has a green to go to ground.. so i had a green from high beam indicator to ground and a green from headlight pigtail to ground... all the photos you are showing me only have one ground from the high beam indicator... i guess the after market headlight unit comes with a green ground that the original did not????

I think you would only need that if you were mounting it into a plastic bucket. The HL bezel should be grounded thru the metal bucket. Or you can connect that green to the frame any way you want.

problems arise when some people are using the original honda parts and some use after market,, confusion sets it.. IE.. original honda headlight had only blue and white wire.. after market light has blue, white AND green wire... thats why i was unsure ans i thought same thing.. no need to ground headlight.. so why put a grounding wire on it..but they did..

True enough however, you're overlooking the basic fact that these machines are closing-in on the half-century mark. The parts support is flat-out amazing, better than what's behind most machinery that is decades newer. Sometimes, aftermarket/reproduction is all that's available...still pretty incredible that an OEM would provide parts for anything they made circa 1969! One should be thanking the aftermarket suppliers for making the sometimes heavy investment needed to keep parts available, they've gotta make a living too. It is still possible and practical to keep these vintage bikes viable enough to really use them, almost like they never went out of production. Some accommodation has to be made. Mainly, that means you have to either source old-school expertise, or learn some for yourself. Most dealership mechanics have be reduced to part replacers, unless they're either older than the machinery, exceptionally dedicated/motivated, or all three.:34:

You have unlimited free access to a first-rate resource, expertise that won't be found in any dealership & folks willing to help answer your questions...this board. Maybe try chilling-out a little, working on one issue at a time, and gradually accumulating enough expertise to keep your bikes going for the next five decades.

FWIW, I know that electrical issues will always be a reliable source of migraines for a lot of people. That's why shops charge big bucks for electrical repairs. Still, it doesn't have to be this way. These electrical systems are about as simple as they get. Tracing one lead at a time is easy, using a wiring schematic. That is the process. Once you've traced them all, you'll have at least a basic understanding of how it all works, enough to make tracking-down problems a lot less intimidating in the future. "Patience, Grasshopper"...

I was a Bell telephone installer and repairman for 35 years. We'd be standing in a pit with mud up to our calf's and someone would always say, nice clean electrical work. After dealing with that these bikes are easy - you get to work on them inside!
