08 gsxr 1000 wiring??
 

So I have 2 wires I have no idea where they go!! There's a red and yellow wire coming out of a relay.. one is I'm assuming the positive for battery the red one.. the solid yellow I have no idea.. these r bigger Guage wire then the rest on harness.. prob 8-10 gauge mayb small but definitely a different from everything else.. anyone kno where they go.. I wanna hear her run please help..

I can't post a pick for some reason but if u wanna email me or txt for a pic to help lmk jyoung8j@gmail.Com or 614-499-2272

Yellow wire with red line is fuel pump. The relay it's coming out of is the fuel pump relay.
Edit... Never mind I read it wrong lol. I will see what I can find out

Re: 08 gsxr 1000 wiring??
 

If someone can help me get a pic posted i have some decent pics to help.. think its a ignition relay cuz the little wire come out of it and go to a switch..

He probably is missing the tracer color. The only Yellow with no tracer wire seems to run to the "Zup Valve Motor"

If the relay also had a small yellow with black tracer>>>> and small orange with white tracer wire>>> along with large yellow with red tracer>>> and large red with blue tracer, >>>that would be great because it would mean that your fuel pump was wired to shut down whenever the engine stopped running.:6::6:

This Is this a cut down harness>>Right?

What you need to do is Google 2008 gsxr 1000 shop manual and down load a copy, sometimes I find them free sometimes they want a couple of bucks, but once it is in your computer it is always free and handy. Trust me you will need it>

I actually had a engineer from my work take a look at it and he found the part number and got the schematic and came back as the red is 12v and yellow is negative so hopefully that is correct thx

If both of them wires are connected to a relay I wouldn't bet on it.

Relays are electric switches that take a small current and control a larger current such as Fan>Fuel Pump> or starter.

One big wire Red with the blue tracer comes from the battery positive terminal it should be hot all the time.

The other big wire goes to a load like fan pump starter. To close this switch and make a path we need a control circuit in the relay.

One of the small wires goes to the ignition switch and turn power on and off to the relay control circuit. The other small wire usually goes to the computer where a device called a driver is turned on by the computer when it wants something to happen. This driver completes the path to ground and causes a small electro magnet in the relay to energize and pull the larger switch into contact and complete the circuit to the load that is desired to turn on.

In the case of the starter the control circuit is connected to a small switch in the handle bar to complete the ground and start the motor with the help of the relay to apply a larger current to yet another larger relay the starter relay. WEW!!!!

Hey dad thx for tht long reply and now I'm really lost lol.. can you email me and I'll send the pics I have and see if we can make some sense of this.. I think my bud is wrong also.. just gotta figure out where they go.. in my pics u can see the switches along with relay and wiring thx j Jyoung8j@gmail.com

Is this a cut down harness?

do only 2 wires go to that relay

where do the other end of the wires hook up to that go to that relay?

check your wires for colored tracer stripes you may have to move several inches from the end to see tracer.

The colors sound like fuel pump but if they go to a relay with only 2 wires something is wrong.

Google that manual and download it.It will tell you anything you want about the wiring.

It's a piece of cake>>>>>>>>Devils Food

In order to tackle electronic and electrical problems you first have to know the fundamentals in order to make any sense of them wiring diagrams.:);) Read it again and then get one of them engineers out to your shop.:6: Show him that diagram you have downloaded a part number is not going to help much.

I sent u some pics dad.. it has 4 wires coming out of it.. one wire going to switch the other to push button... red and yellow just chilling there..

Did not get any pics.
What wire runs to your fuel pump?
Bikes use relays for starters, f pumps and fans.

I see three switches right. one power switch>>>>one fuel pump switch>>>>> I and ass>>ume the round one is a starter button?

That relay has a hot wire red (hot from battery) an orange power wire for the control circuit portion of the relay (controlled by ign power switch)? and a grey wire running to the starter button. Is that correct. Where does the yellow wire go? (probably to the control circuit on the starter relay? I would be guessing.

I noticed 2 wires going to the starter button both black, they are attached to both sides of the starter button. Are these both ground wires? If you disconnect them from the switch and you use a ohm meter do they both have continuity to ground? If so they should probably both be on the same side of the switch. Then when you push the button it would complete the circuit to ground and the relay would energize. If that is the case and you hook the yellow to the control of the big starter relay it will energize.

All of this being said>>>> as big as your starter button is you could do away with that relay altogether your button is 10 time bigger than that little button on a M/C handlebar and should have no problem with the amps required to energize your starter relay all by itself.

Back to the original problems. What is not happening?

Honest Dad himself:6::6:

Ok I'll show my buddy this message cuz I'm no wiring genius..lol I'm just trying to find out where the red big wire and yellow big wire go along with the fuel pump wires.. I was assuming the one switch was power and other was fan since fuel pump wires r just hanging.. I haven't hooked anything up cuz I dnt wanna blow or fry anything.. so can't really say wht it's doing or not doing.. just got car in a basket and assembled it and trying to figure out this mess.. thx j

Engineers take classes on how to make their electronics idiot proof and do a pretty good job of it.

You have a cut down harness and 99 times out of a 100 the guys take the fuel pump relay out, I DON"T KNOW WHY but they do.

The way I see it is you have 3 switches one ignition one fuel pump and a starter button. A wire should run from the battery directly to the ign switch>>>however>>> it often starts at the starter relay. A wire runs from the battery to the starter relay it then runs through the main fuse located in the relay and covered up with a rubber cover to keep it dry. this also provided current to run the relay. on the other side of the fuse the wire runs up to the ignition switch. The ign switch supplys current to the ecm and one side of the fuel pump switch. So when you turn on the ign you energize the ecm and also make it possible to energize the fuel pump through the fuel pump switch. A wire should run from the fuel pump switch right to the + wire on your fuel pump. The neg or black wire from the fuel pump should run to a frame ground or battery ground a better spot.

Now you have energized the fuel pump and the ecm.

Lets do away with that dumb and redundant relay on the dash. Make sure them 2 wires running to the starter button are indeed grounds. If they are connect them together and bolt them both to an engine ground,they probably supply grounds to other components so ground them.

You have already found the starter relay it has 2 really big wires 3/16" or so one goes to the battery and the other should go to the starter. The relay also has several smaller wires several may be hot one of them hot wires runs up to the ignition switch and powers it. One of those wires will be the control to energize the starter relay.

You don't have any wires on your starter button now, you moved the grounds and threw the relay away.

Take another wire fron your ignition switch on the controlled side (on-off) and connect it to one side of the starter button. Hook another wire to the starter button and run it down to the control wire of the starter relay and you should be ready to go, I THINK.:)

Wow.. I'll take a look tomorrow with my bud.. really sounds complicated to me lol.. he prob understands.. thx j

While you have your friend looking at your race car show him this little device. It might prevent you from becoming like that Pilot over in the middle east.http://www.a1racing.com/Longacre4302...FYcDaQodF0wAwA

Well we was able to hook up battery and find out the one toggle is power and turns over with push button.. other toggle we think is for a hot source like aka fuel pump or fan.. still some testing to do tom.. but def closer
