I can't find a wiring diagram on line, anyone know what colour the earth on GSXR injectors is, I just have the bare wires, and the lable fell off while I was testing them.

you should have 4 separate wires,they earth through the ECU,the other thicker wire (4 into 1) is the power supply,got an ohm,s meter?

I have Haynes for mine (GSXR1000) if you want me to scan in a page and mail it you you?

Also obviously have KC sitting outside too (in the bloody rain...) What wiring is it you need? The colour of the looms going to the injectors?

Cheers

I have two wires comming out of the injectors which I am batch firing with an Emerald, I have an ignition switched feed and a switched earth through the Emerald.

Which of the two wires, (bascally yellow or basically gray) do I attach to the feed and which to the earth.

I knew once, now the lable has fallen off.

I spose it might not matter. (tries to remember his basic electro-magnitism.)

Found a 'busa manual in the library, the yellow wile goes to all injectors, the fule pump and lots of other things, the grey goes back to the ECU, so I'm assuming that is the switched earth.

I'll see how that goes.
