The infamous Gray wire..Need more info on location

[paparick33]

Still not entirely sure on which wire to pull out???

Is there info on this in the service manual???

[HaremScarem]

under tank towards front right side, 2 wires in connector,1 black and 1 grey

Thanx man..i found it (only freakin gray wire under there, can't believe it took me so long).

Next question.....how the heck do you get the wire out????

2 wires 1 black 1 grey? i thought it was in a 6 wire connector.

I know the 02 426's have a 2 pin connector. 1 wire black and one grey, which are in line with the CDI unit. The black is connected to ground with the ignition coil and the grey is a return to the CDI. The six pin connector on 02's have only five wires and no grey conductor.

I should have asked which year bike he had before responding. Hope I caused no trouble ?

Yeah I got confused on this last night. The WR450 has a 6 pin connector and the grey wire is in the middle on one side. www.offroad.com has a WR450 site giving tips on the grey wire (WR450 project bike). The site has a great picture of the WR450 connector in question. Even the shop manual confuses it even more, it shows the grey wire going to ground all by itself - not the case.

No guys it was my fault for not saying which bike i have. It is a 02 WR426, and i did find the 2-wire connection. Thanks for the help on it, but i still can't get the wire out of the connector. I know you shoudn't cut it, but it's a task trying to get it out.

[HaremScarem]

AHHHH Just cut it ?

Want to do grey wire mod on mine. Where and what to look for on my 99WR400F?

Do the 01 WR426's have the grey wire? If so where is it?

[MN_Kevin]

I cut the sob since I have no desire to have my bike run crappy.

[426Woodsguy]

I'm with you Waterski, Where is it on the 01 WR426?

I thought my bike ran great, am I missing out? ?

Removed the grey wire on my 03' wr450 yesterday. Only grey wire in connector of 6 under tank. Pulled the wire out of connector by lifting release tab with small screw driver. What a difference. Of course I rejetted and cut the throttle stop at the same time but the bike is much more powerful now. ?
