replacing left switches...wiring issues

[match417]

So basically i have yzf600 switches going on the FZR. everything is pretty simple, except for the turn signal. The fzr turn sig has 5 wires and the yzf has 3. The extra two wires are ground and another wire from the relay. I took the whole switch assy apart to trace the wire and see what's going on so i can do a better job at working the yzf switches in. But that didn't help much. It looks like the yellow/red wire and the ground are pointless. Will the turn signals work if i don't connect the yellow/red wire and the ground? Or do i have to split both wires and wire them into something? Can someone go and cut their wires and tell me

Im not really sure but have you had a chance to compare the two wiring diagrams to see each wire and what they go to. you might be able to figure it out through the service manual wiring diagrams. I have the fzr but not the Yzf one if you need extra help.

Just in case you are missing one of these. I'm not sure how much it helps though.

FZR Wiring Diagram

YZF600r Wiring diagram

That helps me. I can take a look at it in a little bit to see the differences.

you should have used 05 r6 controls!

thanks sweek and 95, but i have already compared the two diags, i have a lot of yamaha manuals. That's how i noticed that there are two signal wires going to the switches from the relay, but it still needs a rewire of some kind. I was brainstorming today while looking at the inside of the switch trying to see how i could rewire the inside to look like the in side of the FZR switch. The yzf setup has a separate relay/flasher that i found on ebay for $20, and i can probably get from the yzf forums for cheaper, but i'll just make something from napa parts and make my own flasher system.

shred,
that switch doesn't have a choke on the h-bar. 05 YZF600 does. so i'm utilizing that. I don't like the choke beside my knee.

Do the 99 - 02 r6 controls have 5 wires on the turn signal? With choke on the h-bar? I'm gonna have to look into that. Too late now, plus it's too hard to find people parting out 1 gen r6's.

Hi,
OK wild guess here.
The 5 wires switch are:-
one each Lh & RH front
one each lh & RH rear
one ground

the 3 wire
one left hand
one rh hand
one ground

Thus you find out which on the three wire switch is left hand and make a splitter to match your FZR harness

Then you find out which on the three wire switch is Right hand and make a splitter to match your FZR harness

Ground to harness ground.

As I said wild guess but it would be what I would try first.

i wish it were wired that way, but the left front and left rear are wired together, so is the right side. two wires are signal wires from the relay, one wire goes to the left bulbs, one wire goes to the right bulb, then there's ground. I've followed all of the wires in the wiring diagrams for both bikes. The YZF has a separate relay/flasher that one wire comes from, then the other two wires shoot straight to the left side or right side.

Inside the switch assy, 3 of the 5 wires are directly behind the switch, middle wire (brown/white) is from the relay, right and left (brown and green) wires go to the bulbs, the left two are connected when you push left, and the right two are connected when you push right, completing the circuit and flashing the bulbs(in theory). But then there are the other two wires, one more signal wire from the relay pack, and a ground wire. There is a two prong fork looking piece that the stalk behind the switch sits between. The ground wire (black) is grounded to the case of the metal switch assy, the other signal wire (yellow/red)attaches to the fork, and the left fork prong is bumped if you press left, or bumped on the right if you press right. When the switch is pressed all the way left or right, the signal wire from the relay pack connects to the ground (via the fork) until you release the switch, so it's a momentary connection, not connected while the blinker blinks, but the two wires that i was talking about in the first sentence of this paragraph that are connected stay connected until you press the turn signal button in, then it snaps back to the middle (off). I just drew a picture of what's inside the disassembled switch. So read what i typed above and look at the drawing. The bottom half of the drawing is the bottom side of the assembly, the top half is the top part of the assembly.

Black is ground
yellow/red is a signal wire from the relay pack
green goes to the left bulb
brown/white is another signal wire
brown goes to the right bulb



so with everything i just typed, someone please tell me WHY yamaha decided to use 5 wires when 3 would do the same job. Why are there two signal wires? I'm about to just say "screw it" and get the whole YZF electrical system, plug in my TPS that's hanging off the carbs and get some YZF gauges. But i would need money.

[match417]

EPIPHANY! maybe one signal wire from the relay pack turns the bulb on, and the other signal wire from the relay pack is the flasher. It's stupid, and requires more wiring, but that's the best explanation i can come up with.

but i still don't know..can someone please just go and clip their yellow/red wire and see if the blinkers still work? I know i know, you're clipping one of your wires, but the FZR world will be better with this one sacrifice, just wire it back with a butt connector and it's like it never happened. I would but my switch is in pieces and i've already started wiring the FZR harness plug to the yzf switches.

-----------------------

EPIPHANY # 2!
can someone go do something for me? go to your switches, press barely to the right or left so the signal comes on, then release it. If the signal doesn't stay on then i think i know how this thing works. I think the yellow/red signal wire holds the blinker so it keeps blinking, and if the switch isn't pressed all the way then it doesn't hit the yellow/red wire. So it won't keep blinking.

FZR wiring :-

OK wild guess here:-

The 5 wires switch are:-
one each Lh & RH front
one each lh & RH rear
one ground

As I said wild guess but it would be what I would try first.

OK revision to my guesswork:-
one wire is for both LH lamps
one wire is for both Right hand lamps
one wire is the "signal" wire.


You need to obtain the YZF relay as that is power / grounded at source and just supplies the "FLASHING signal of ON / OFF." to the YZF bar switch.

Then as i said you just make splitters to go to the FZR harness.@ the bar end

The tricky bit will be at the relay end but the wiring to ground and hot line will at least to hand.

When I wired in the oil light to my r6 gauges I had to install a relay but I used one from autozone and so far it has worked out great. That may be what you have to do. I looked at it a little last night but need more time to help you.

[match417]

problem solved, twist yellow/red (from relay) and ground together, then wire the three wires into the turn sigs on the YZF switch..works fine. Turn signals only come on and go off if these two are twisted together. Still not sure how it works, but i know this is how it has to be done.

iv got no extra relays on my bike, but my oil light works...



as for you match, I like the whole choke on the control thing.
you can only do that with the yzf carbs though...
after you get the carbs on you should dyno it and see if it makes any diff....

[match417]

actually, you can do it with anything. The choke attaches to the carbs on the FZR and on the YZF the same way. It's just that the YZF cable is longer to reach the hbar

[shredex]

after this you need to get started on the r6 front conversion!

also
match, did that relay work out for you?
you never said anything about it.
