Hi guys,

can you help, i have a gen1 with the yamaha PIAA lights fitted under the headlight as a gen 1 they are halogen bulbs, now i am removing these lights 2 put a mictunning 6 inch led light bar in its place.
Now i,ve mentioned in another thread that these 2 lights are off, and the 1 lead going to the one light is tapped up and put away, the other lead is going to be conected
to the led light bar,
now these yamaha lights were connected into the yamaha 3 pin plug that is there in the wiring harness waiting for them, now my question is if the 3 pin plug in the wiring harness is on the bike right hand side for fitting these lights, then WHERE WOULD THE FUSE BE,

i,m asking as taullpaul, said that the fuse would need changing as the halogen bulb would need a different fuse to the lesser led light bar, my concern
is looked in the hand book at the fuse block can,t see a fuse mentioned for auxillary lights, but if that jack plug is built into the wiring harmess it should be yes

any help please

From memory what i did was just use the factory plug as a trigger for a relay and powered the lights off that relay.

hi mark,

that link above doesn,t mention fuse
mine are plugged into that 3 pin white plug thats in the harness for them no problem the 2 lights i removed leaving 2 leads, one lead i,ve tucked away, the otther lead has 2 wired white/black these lead i,m going to fit my led light bar like yours to it, now taullpaul says the fuse for the halogen bulb will be to stronger for the lesser led light bar i was going to just fit it.
but if that white 3 pin plug is already in the wiring harness for these lamps wheres the fuse to

Main lights is what i mean.
if the main light fuse covers it you may be right, that would mean if the aux lights popped it you,d have no main as well yer, if that fuse does cover main lights plus yamaha auxillary lights , if you fit a lesser led light bar the fuse will have to stay as is if itcovers the main as well

can you honestly see there being a issue i,m on stop now fitting the led bar, my yamaha lights were fitted by yamaha into that 3 pin plug ok, i,ve removed the 2 halogen lights one lead is tucked away the other lead is going to the led bar but because paul said change the fuse over as the halogen light was drawing more current than the led drawing less i,m worried i was just going to wire it and go
but can not fing any info on fuse

This might help get you started.
I just looked up some notes I had on this and found a link that may help.
.

OEM Aux Light Plug (3 wire)
Red/white - 12V unswitched power (20 amp fuse)​
Brown - 12V switched power​
Black - Ground​

The Red/white wire would be power for the lights and would be on fuse 12.
fuse 12 - O/P (option) fuse -- Reference Owners Manual p 7-31 and 7-32


I didn't look at the whole thing but this thread may be useful to you:

sparrowhawkxx,

thanks so you are saying that the 3 pin plug in the wiring harness for auxillary lights has a fuse in number 12 of the fuse block whitch is marked option, i take it if there is no aux lights this is left empty if there is a live fuse in there 12 that is you have these lights

yep i see 12 says 20amp fuse so these auxillary yamaha lights are fused there 12 are they, if so paul told me to put a different fuse in as the fuse is for the hlogen bulbs and a 8 inch light bar led would draw less current if so do i pull that 20 amp and reduce the fuse there if so to what a 10amp any ideas

Why not replace the original Yamaha lights, turn them to ensure everything is working. Turn them off and pull fuse 12. If the lights are not working now you've found your fuse.

Hope this helps

A 3 amp fuse would be my suggestion. Always go for the lowest rating you can that is the next size up from the current being drawn. The fuse is there to protect the wiring if the item being being powered screws-up. In the event of said screw-up the wiring harness will not be melted because the fuse blew and protected it.

I can't even get to my bike to check! I'm having some work done to the house so I've had to put my bike in the workshop, where it's now buried under loads of other stuff.

if you read annswer #9 sparrowhawkxx is saying that the fuse 12 is what they use if you plug the lights into the 3 pin auxillary light plug in the wiring harness fuse 12 is option 20amp
