I've just finished cutting my injector wires and re-soldering them into my traction control loom. Started the engine and all seems fine, each injector is clicking away nicely.

 

But then I thought, how would you know if you had accidently connected the wrong injector to the loom? I was using the plug method to install the loom so that I could unplug it if need be.

 

If the injector was connected wrongly i.e. inj1 signal on the ecu side got connected to inj3 signal on the engine side. The injector would still fire as it's getting a signal from the ecu. But would this cause a problem and would you be able to tell?

 

I haven't mixed them up, so just wondering really.

Aah, that makes sense. Cheers dude :)
