So I have been trying for the life of me to hookup a single H4 halogen front light to a system that was previously a dual H7 lighting system.

The original two connectors looked like this: http://imgur.com/DgFZ0GX

The new connector looks like this: http://imgur.com/FlrmADi This is the original schematic: http://imgur.com/MMp9BoP

This is what I did to the wiring, I disconnected where the light wires connect to the dash controls(because I upgraded for a computer system) and I split off the other bk/y wire off the first light to give me 3 wires to connect to the new connector? : http://imgur.com/mwEPcxV

This is the schematic for an earlier Kawasaki KLR that used a single light: http://imgur.com/maZOS02

My question is where do I need to connect the black/yellow [(-) ground] the red(lo beam) red/black (hi beam) to allow the light to at least work if not allow me to switch back and forth from high and low beam? Also I did originally connect the wiring in a way that I think was wrong and when I went to test my work by turning the bike on it made a pop and now the bulb has a little black spot by the connector, could i have fried the bulb too? Thank you in advance, electronics aren't my strong suit!

Sounds like you may have fried the bulb.

You will need only one ground. Check out this image for the pinout


Common is your bk/y, high is your rd/bk, and low is your Rd
Which should be green--bk/y, Blue--rd/bk , and white--Rd

You can twist the rd/bk's together, or just cap one of them off.

If you arent using a city light, cap those wires off individually.

test the bulb on a test lead if you arent sure if you blew the filament, or just try a new one. If it still doesn't work, check your fuses.

EDIT: Looking at your pics again, it looks like you have two rd/bk due to your city light. You can cap off the one from the city light if you aren't using it.

Something seems fishy in that schematic. I don't normally see city lights wired to the highbeam circuit. Then again, I'm in the US, so I don't normally see city lights.

Thanks for the help! the second rd/bk is going to the light that was in the dash for signally if you had your highs on. When I rode around in low only one light was on (city light?) and high both would turn on. and I didnt cap that wire I removed it all together because I removed the dash board circuit all together along with the second bk/y from the second light connection leaving me with just one bk/y one red and one rd/bk.

I also think I tried the wiring you are suggesting, the second time so I am pretty sure I fried the bulb:oops:

Ok, I get it now. I thought the little bulb in the "original schematic" pic was a city light (like in the other schematic you posted) but its the dash indicator.

with that cleared up....

The thing that is puzzling me is that even if you hooked everything up to the bulb incorrectly, it shouldn't burn out. It may not work correctly, but there should not be any combination of incorrect wiring that will blow the bulb. Its possible that the bulb housing is grounded and connected the "common" pin to power may have blown your fuse, and could have left a burnt mark somewhere.

As long as you hook the bk/y up to the "common" pin on the bulb, the other two connections don't matter (other than the switch being backwards).

I would check all your fuses and go from there.

Dude thank you so much! The wiring worked perfect and like you stated the fuse was the main problem and probably the source of that initial "pop" I heard. Fixed the fuse, wired up the headlight and turn signals and took her out on the maiden voyage around chicago for the first time! thanks for the help brother!
