Hi guys

I have a Hayabusa E-03 question. The E-03 is the version without the immobiliser (USA market).

The ignition barrel was smashed by some fuckwit that didn't notice that the bike was chained up.

The old ignition barrel has 6 wires - the replacement (from a wreckers) has 4.

I've checked the wiring diagram (http://kaele.com/~kashima/car/busa/GSX-1300R_E-03_Wiring_Diagram.pdf) and one of the two extra wires go to the immobiliser pin on the ECU but just provide a "switch on" signal, rather than a coded immobiliser radio signal. The two extra wires are Bl and O/Y.

The Bl wire connects to O further down the loom anyway. The O/Y wire goes to pin 21 on the ECU. When the switch is on, the diagram says that the two are connected.

Can I get away with leaving these two connected all of the time or will the ECU loose its shit? Also, I assume these are "always on" when the switch is on and don't provide an impulse when turning the key?

Help is much appreciated.

Ordinarily, I'd test the old barrel with a multi-meter and see what does what when I turn the key but I can't get a key in the damn thing.

Also really struggling to get the old barrel out.... I have the correct torx adaptor but getting access to the bolts is an utter bitch. Any ideas?


And yes, just to double confirm - a USA spec Hayabusa does not have an immobiliser. Suzuki didn't believe me when I said it didn't but once they checked my VIN, they confirmed it didn't. Where the antennae would be is a piece of rubber.

You might need to do some research on the secondary feeds to the ECU, some of the jap manufactures fit a zener diode to the secondary wires feeding the ECU. They do this so the output of the secondary wires is somewhere between 5 & 9 volts. This is to stop the bike being hot wired by just twisting the wires together. If the ECU gets a voltage feed to the secondary wires that is not correct it shuts down the ECU. You should be able to see the zener of you can get the switch apart.

I do.

$500 excess instead of $200 for parts from a breakers.
