Hello,
Im very inexperienced with electrical work and am in the process of installing new K Suspension injectors and need to wire in new pigtails. The new ones have a red and black wire but the old wires are white w/blue stripe and green w/red stripe. Best I can tell is that these are not the stock wires or even the proper ones for that harness.

I’ve spent the last hour searching my manual and Google to identify which wire is what but I’m not finding what I need. Any help is appreciated!

Get a meter. One of those wires will have 12v when the key is on. One will have no continuity to anything.

The injectors get 12v all the time the key is on. To fire them, the PCM provides ground at the correct time. It adjusts fuel mixture by varying the amount of time it provides ground.

So, when you find the one that has 12v, you know that's equivalent to your red wire. The other is automatically the ground wire, or black.

The green/orange is the ASD relay feed and should be 12v.
