Ignition to ECU signal wire (The Troublesome Pink Wire) CBR929

In this video I go over reading the voltage of the signal wire from the ignition to the ECU. I also included a few clips of how to wire in a 12v to 9v converter in order to fix a no voltage problem or a 12v reading on the signal wire. I also included a diagram of how to test this signal with a 9v battery.

If you do not feel comfortable with electrical or wiring, please find someone qualified. The diagrams were quick and dirty, so please use caution. Read out your own voltages and make sure you are using the proper pins for your connector. I tried to be as detailed as I could but I'm sure I've missed some details so feel free to ask.

the best way to contact me in regards to these questions would be on this thread.

Good video, Thank you for taking the time and effort in keeping us all in the loop. I've found this very very helpful indeed ❤❤

Thanks to your video I repaired a cb600f hornet, which has the same problem with the pink wire. You can recycle the diode from your old keyswitch, as I have done.

i agree with these other guys comments thanks for putting up this video. it saved me from buying the expensive switch.

Great writeup and awesome diagrams. Do you know what the diode part number is and where it can be bought?

Man I’m having a problem getting my 929 running and it felt so good to hear her fire up with the 9 volts. Prior to this the bike would crank but not fire?

Hi. Sorry I know it's long ago but would you or anyone be able to help me with where that pink wire goes into the ECU?

I'm putting one of these engine in a hillxlimb bike, won't have a ignition switch just a starter button, do I need to feed that pink wire. 9v?
@michaelthomas4182 2 years ago

I have that problem but aftermarket switch has only two red wires one with white line would it still work
@abigailcraven5149 2 years ago

so 12v to 9v 3amp converter should be fine?

So would I just cut the pink wire and put a 9v battery to it?

Okay I have a 02 f4i got new pump in it and it was priming loud and strong but no start no start no start charged the battery up all day came back out and same thing until it stopped priming again??? I resaudered that diode in ignition just incase still no dice, I just volt tested DC20 red pos lead in pink wire where connectors go and I used a ground at my stem I’m getting exactly 9.97 volts is this good?
@michaelthomas4182 2 years ago

Does this method work for a 08 cbr600rr????????????????????????
@eliomiceli3639 1 year ago

I have the same problem with a 2002 Hornet CB 600 F, I disassembled the diode is the original code is: 3.9 B2 (may be helpful ☺)
@goldenboi7685 2 years ago

Why not just replace the diode?
