09 keyless ignition mod

Since my bike is strictly tracked, I decided to delete the ignition. The following worked for me, and I found useful info on this site but do this at your own risk :D

The wires need to be found, cut, and spliced

at the ignition

brown... this is the wire that becomes energized when you turn the key on
it goes from the ignition to the 15a ignition fuse

White... this is the wire that supplies power to the ignition switch; it is energized even when the key is in the off position. It goes from the 30a main fuse to the ignition switch.

Gray... this is the wire that sends a "signal" to the ECU when the key is turned to the on position. This wire needs a 100-ohm 1/8-watt resistor spliced into it to "trick" the ECU into thinking you are using the keyed ignition to start the bike.

OPTIONAL red... I reused this wire so I could power the accessories that I use on the track, my GPS based lap timer, and my hi-def GoPro camera. This wire, in its normal state, energizes your left and right front city lights and, in the rear, your tail light and license plate light. It energizes when the key is turned to the on position.

at the start stop switch

Yellow/red wire... this wire supplies power to the start/stop switch. It comes from the 15a ignition fuse and is energized when you turn the key to the on position. It is energized regardless of the position of the start/stop switch.

Red wire... this wire becomes energized when the start/stop switch is in the start position. It goes to the fuel pump relay, coil wires, and to ECU.

o.k., let's start cutting...:buzzsaw:

The location of the two plugs to access the wires is under the tank and airbox. We are looking for the ignition connector and the start/stop connector.

Here is the ignition plug

the start/stop plug

I cut the white, gray, brown, and red wires. Remember, red is optional

Cut the yellow/red and red wire from the start/stop plug.

now on the ignition plug take the white wire from the plug side and splice it either wire from the start/stop switch, i used the red wire from the starter switch. take the gray wire from the plug side and attach the 100 ohm resistor

Image


now all that is left is the yellow/red from the start/stop switch and from the ignition plug the gray with the resistor, the brown which will power your ignition fuse and my optional red which will power my accessories. i twisted the 3 from the ignition plug together and soldered them to the yellow/red from the start/stop switch. some shrink tubing and electrical tape to finish it off plug both connectors back in

fired it up and it all worked out somehow:dunno:

Thanks for the writeup. Got mine all setup tonight. I tried to do it without the red wire. After wiring everything up I pushed the start button and it turned over so I thought I was good. Soldered and heat shrunk everything up and put the airbox on. Plugged in the tank and hooked up the fuel line and it wouldnt start. Checked and double checked everything. Took it all apart and plugged the ignition back in. Started up no problem. Tried setting everything up again about 5 times. Then after a couple hours I realized duh the optional red wire needs to be hooked up to power my Bazzaz kit. I guess I had hooked it up to the tailight for power. Hooked up the red wire and bam it worked. So if your an idiot like me and forgot you have accesories hooked up it probably best to go with the optional red wire.

Top write up! REP sent!

Might have to try that on my 09 if someone find a way to remove the ignition assembly... I have no problem turning a key on my track bike but if I can lose some weight by removing parts I'll do it.

You can remove the actual electronics by taking out two tiny torx bolts, this includes the bottom of the ignition assembly and the wires. To remove the entire ignition assembly you have to drill out those bolts or try using one of those stripped bolt tools since they snap off the heads of those bolts from the factory. To me thats not really worth it but I removed the bottom piece and wires just to clean things up.

I relize that this is an old thread, however I need to Know how to do this on an 03 500 ninja. I am using this engine off a wrecked bike for a off road buggy. The wiring I have is everything but the ignition switch and the start/ stop buttons. My plugs are different then the ones pictured. Could anyone tell me how to rig up these switches? All help appreciated.

Youre not worried about running all that current through a switch & smaller wiring that isnt rated for that much amperage?
