Just received my terminator x max ans as I was wiring it up I noticed the injector harness has two connectors labeled #3.
Does anyone know hat are the wire colors for the #1 and #3 injector plugs? Thanks. Both labeled injector 3🤣🤣🤣🤣

Yes, follow the schematic and will have to check each one with a multimeter for continuity to make sure they're pinned correctly.
It's unfortunate that holley's harnesses are having this common problem with whomever is building their harnesses. I was helping on guy on fb who's harness was completely screwed up. He had to send it back and wait 2 months for a new one. But it seems they don't really care about the problem. It's still happening and they're still making million$.
Quality control is far down the list.

The letters identify the cavity. Cavities are either labled with letters, numbers or both depending on the amount of cavities. But you will need to trace which wire goes to which injector.
But unfortunately you'll have to call Holley, sit on hold for 10 to 60 min, then get a guy who might be at home cooking dinner like my guy the other day with kids screaming in the background, to get a straight answer. But hopefully someone on here knows already and posts up.

You're making it much harder than it needs to be.
If he looked at the link I provided it had the answer he was looking for A= is injector1 B=Injector 2 C= injector 3 and so on.
Then you look at the diagram
A is Gray
B is White
C is Beige
If it were me, I would printout the diagram and get someone to help and ohm out the whole harness after finding that issue. It doesnt take very long and then you would know for sure.

The thing that's important here is what letter corresponds to which cylinder. Is A, B, C, D = 1,3,5,7, or 1,2,3,4?
Without seeing the schematic for the actual injector harness, you don't know. Or start probing.
I see what that said in the description, But I'd be afraid to trust it with his issue.

I posted it in my response earlier "If he looked at the link I provided it had the answer he was looking for A= is injector1 B=Injector 2 C= injector 3 and so on."
It's all on the Holley website and it really doesn't matter what harness it's all on the outputs of the ECU, You can literally make your own harness with the diagrams they provide. If you know how to read a wiring diagram then it's simple to figure out what goes where even without a color code.
You guys are a big help. My wife is going to blow up and print out the schematic and im going to go through the entire harness. Thanks again for your help.
