So Im putting a 99 gsxr 600 motor in my 97 gsxr 600. So far so good, except this one plug. The plug from the 97 600 wiring harness on the subframe has 2 wires going into it. The plug off of the 99 600 has 3 wires and the plugs are different on the 2. The wire on the motor appears to be going down to the motor right in front of the sprocket cover (I followed them down on both of the motor to make sure that it is the correct plug). So my question is does anyone know what this plug connects? and what would be the proper way to connect these wires? heres some pics of the 2 plugs

Heres the 2 wire plug coming from the original wiring harness



Heres the 3 wire plug coming from the 99 motor



and heres a blurry shot of the insides



I turned the motor over, but have not tried to start it yet since I do not know what this plug is and do not want to take a chance of damaging anything. Any help would be great on this. thanks

Yeah, I have my 97 service manual. I doesen't go to the speedo cover, it goes just in front of it (like more around the water pump area). I'm gonna have to look closer at it tonight and see if I cant figure out what it is. Ive been looking at the wiring diagrams and having difficulty figuring out what the wires correspond to. I thought maybe someone who's torn apart a gixxer might know what this plug goes to so I can identify it on the diagram a little better.

You can't tell how many wires from this diagram, but its basically what tells the ECU, what gear the bike is in, to change the maps, and/or trigger the neutral light. Its #45.

They show it being the same for all of the following bikes, if its the thing I am thinking of ...but yet, you have a harness with a two wire plug and a plug with three wires?? LOL

The wireharness is har to look at and get an idea...they have, for both bikes, a 97 & 99, what looks like two side stand switches. WTF?

That looks like the right plug, it is the only one with that shape (as in the pic) on the harness. I understand the neutral light/sensor, but what do you mean about changing the maps? My bikes carburated, would it still do this/just be a neutral sensor? It doesent appear to be too crucial so I think I can go ahead and try to fire it up without this. I want to hear the motor running since I have not been able to start it up since I bought it. The extra wire on the new motor is black w/a white stripe so Ive been wondering if maybe they just added a ground wire? Thanks for the help DougZ.

Zuki usually does make ground wires black with white tracer..in either case..I don't think it would hurt to start the bike with out that hooked up..I think..if the bike blows up...not my fault. LOL My guess, since you said its carbed..my guess its just there for the neutral light then.

I diden't think that it would be a big deal starting it without this plug connected but I wanted to figure out what it does before I attempted. Just to play it safe. Im thinking it probably does just what you said. I figure I can now go home and see if the neutral light is working and if it isent then thats most likely what it does. Thanks again for the help DougZ.

LOL...yeah, just physically make sure the bike is in N, and you can roll it....hate to see you rocket it across your yard or driveway. Good luck with it bro, and NP for the help. That's what we are here for. :rock:

LOL, well the backs on jack stands anyways so i should be safe. I have had that happen before though. I let my roommate ride my bike a while back and he left it in gear (I always park it in neutral). Well I was standing next to the bike in the garage. Fired it up to let it warm up a little before I left. When I let go of the clutch the bike took off on me. Luckily it was in the garage, it kinda climbed part way up a wall and fell on its side and died. It was pretty funny (especially since my paint's rattle can so no damage was done). A quick comparison of the plug and that diagram and Im gonna try and start her up tonight. Can't wait to get back on the road. :rock:

That is the gear position sensor plug. I had the same problem on my SRAD. I just wired the pink and blue wires up without the plug using connectors from the parts store. Mine works fine.

That's kinda what I was thinking...but I wasn't sure, and I didn;t want his bike to implode if I was wrong. LOL :rock:
