TRACING INJECTOR WIRES FROM THE LOOM.WHICH WIRE IN THE ENGINE BAY WORKS OFF THE IGNITION +12V

2007 Audi Other • 35,000 miles

Hi, I am busy installing a water methanol kit.
I need to tap into the injector wire, any one.I have accesed the main loom which holds the wires.I need to verify which colour wire is for the injector. From that, which one is positive, and which one is negative.
Also, I need to get an ignition wire in the engine bay. So far all the wires I found in the fuse box are constant 12v.

Thank you
