I removed the intake manifold and fuel rail assembly to replace the breather box and some other things in there, and absent mindedly didn't label which injector wire goes to which injector. I realized the mistake when I put it back together. Two of the wires are longer and two are shorter, 1 or 4 and 2 or 3 respectively, but I don't see how to tell which is which. Is there a way to?

I know I could just start the car and see how it runs, however I just put in a brand new VX cam as well. I want to break it in correctly, which means bringing the engine to ~3000RPM and keeping it in that range for a while. If my injector wires are all mixed up that'll be difficult.

So, is there a way to trigger each individual injector to tell which wire is which? Some test mode I'm not aware of? Or even some way to trace the wires and tell? The car is a 91, LH2.4 car.

Thanks for the help with my bone-headed mistake!
