Topic: Wiring question

Im trying to wire 07 gsxr 600 handlebar controls to an m unit. i cant find a diagram for the gsxr, does anyone know where to find one or know what color wires are what?

I MIGHT be able to help you out, I'm pretty my left controls are '07 GSXR 600 and it was hell trying to find a wiring diagram online. Pretty sure I have it printed out though in my shop I'll double check tomorrow when I'm there.
What colour of wires do you have coming out of the controls? I'll compare them to mine and do some digging. Or post a pic of them?
If you got some time to kill though just image search with keywords like k7 GSXR 600 2007 etc. Some of the wiring is transferable for say a '10 GSXR 750 or something too so getting the colours of the wires helps a lot when narrowing down a diagram...

Do you have a  multimeter?

Are you planning to use an M-Button? If so, I would reconsider that choice. I have seen numerous efforts to make the M-button work with our older bikes not be successful and end in abandoning it, then go straight to wiring the GSXR controls to the M-unit.

EVERY wire from the GSXR needs to behave as a ground. So, for your TURN MAIN, ground that wire. Then the Turn R and Turn L color will function properly. You will not likely get the "Flash to Pass" feature on your control to work properly. You also need to setup the M-unit with the proper MENU - 5>CONTROLS-> (Try C first).

By the way, it would be helpful to know the exact bike model and year you are working on...

no i am not using an m-button. the controls are from a 07 gsxr 600, and the bike is a 77 cb750k. im making a harness from scratch, and am using led turn signals, nothing is stock. just trying to figure out what colors from the controls run what. i know the controls will be used to just switch the ground side, just dont know what colors are for what from the gsxr controls. if i cant get the flash to pass to work, i will try and just use it to switch through the motoscope mini screens.

I got my flash to pass working fine, all controls work as they should. A 9V batter and. Test light work wonders, that's how I wiring mine after sourcing what wires were which...
Another thing you can do is pull the controls off the bars and see what wires are going to which, that'll help sort most of them out, in junction with the 9v and test light...

Is that with an M-Unit?

this is the only thing i found close to what i am looking for. after taking both controls apart and testing some of the wires, here is what i have come up with. i was a little confused on the right side controls, not sure if i got it exactly right.

Left controls:
 Turn Signals:
LBl----------ground
Grn----------left input on m-unit
Blk----------right input on m-unit
 Horn:
Blk/Wht----------ground
Blk/Bl----------input on m-unit
 Lights:
O----------light input on m-unit
Wht----------ground
Y----------ground


Right Controls:
 Kill Switch:
O/Blk----------coils -
O/Wht----------ground
 Start:
Y/G----------start on m-unit
Y/Wht----------not used
O/R----------not used
O/Wht----------ground
 Brake switch:
Blk/R----------input m-unit
Blk/Bl----------ground

[calj737]

Left controls:
 Turn Signals:
LBl----------ground
Grn----------left input on m-unit
Blk----------right input on m-unit
 Horn:
Blk/Wht----------ground
Blk/Bl----------input on m-unit
 Lights:
O----------light input on m-unit
Wht----------ground
Y----------ground


Right Controls:
 Kill Switch:
O/Blk----------coils + I question this. 12v to coils should come from AUX
O/Wht----------start on m-unit
 Start:
Y/G----------starter solenoid This is not correct. START from m-unit to Solenoid. This wire would be abandoned or tethered to ground.
Y/Wht----------light input on m-unit This is duplicating  Left side O.
O/R----------start m-unit I disagree
O/Wht----------start m-unit I disagree
 Brake switch:
Blk/R----------input m-unit
Blk/Bl----------ground

Can you shoot a picture of each GSXR control so I can see the buttons?

With modern controls, there are often "main" wires to them and several splits for other functions. Usually, these splits are grounded for the M-unit to behave properly. But I have never seen multiple "START" inputs function properly at all.

[spiffy587]

yeah i was confused on the right side wires, not sure if all had to be used. i knew some of the wires were main wires, just couldnt wrap my head around what is what without a real diagram. i have the right side apart still. i didnt take the time to sit down and go through the wires on it yet. so im assuming one of the wires should be grounded, then another to the input side of the m-unit, and more than likely the others will be grounds.

[spiffy587]

updated my post from earlier, will try and mess with the controls and test the wires in a bit. hope i get it figured out soon, i want to wire the bike already. would have been much easier to just have gotten the motogadget switches, but i like the look of the gsxr ones.

After testing the wires with a multi-meter, this is what i have come up with. not sure if the kill switch will work cutting out the ground for the coils or not, but i will give it a try.

[calj737]

The way you have the RH switch described (and the source at DTT) providing input to the coils will NOT work.

The coils received their "ground" from the ignition plate. The scheme you describe is providing a ground also. Your intention (and perhaps theirs) is to provide power thru the KILL switch that is interruptible when needed. This is also an embedded feature for he M-unit that you can double-tap the START button and KILL the ignition.

AUX is designed to deliver power to the other systems on your bike. IF you want to somehow utilize the RH KILL function, use AUX->RH O/WHT-KILL->O/BLK->Coils. Or at least "TEST" this scheme with nothing else on the RH side connected.

You also need to make sure the RH control wiring is at least 18AWG to carry the amperage for the coils.

[spiffy587]

yes that is what i was intending to do with the kill switch. i was unaware i could run it through the m-unit and use it as a kill switch. maybe i should have looked at the m-unit diagram too. the O/Wht is spliced into the contact portion of the start switch when depressed. the O/Wht and Y/G are essentially a complete circuit when the start button is pressed. im using 16AWG wire as thats all napa had available in colored wire at the time, probably overkill for everything.

[calj737]

Just a clarification: you can interrupt the power delivered by AUX if run through the KILL switch as it then delivers that switched power to the COILS. Or you can use the double-tap method via START. (Just making sure its perfectly clear).

16AWG is pretty thick stuff to use with the M-UNIT, especially out of AUX. You'll need at least 4 taps out of AUX: ignition, license plate, tail light, gauge power. MG sells an AUX plug for such a situation and I recommend that item to everyone. You can send service feeds by color to your end components consistent with the stock color diagram for troubleshooting too.

[spiffy587]

ok i think i get what you are saying, to run the O/Wht from the kill switch to the AUX port, and the O/Blk from the kill switch to power the coils. since the O/Wht is spliced to the O/Wht of the start switch when pressed, i would need to take that splice out then, and run a separate wire off of the O/Wht of the start button to ground, and the Y/G to the start input making it just a momentary switch to ground? essentially separating that splice as it was originally intended to switch power as one. i have seen that AUX plug, can i not use the brake output for the tailight? im running an led strip, i thought the m-unit has a function to run it as a brake, and running light?

[calj737]

Yes to all your points.

[spiffy587]

i will give it a shot thank you calj737.
