Please help identify wire color coding for fuel rail pressure sensorHey, These wires

Hey,

These wires are color coded. Can someone identify the order from right to left or left to right? I'm wiring a pigtail ATM to replace my connector that plugs into the fuel rail pressure sensor.

Here's an image of the wires and their colors, you could probably take a look at your own car and compare.

I believe the order is as shown from left to right. Black/blue, blue/black, yellow. I'd like to know for sure though before I clip them and then wire them with the pigtail.

EDIT I tried black/blue, blue/black and yellow and got a short code, so that's not the order. Blue/black black/blue yellow?

FYI if anyone is curious this is the module 2 harness.

Correct order from left to right is Blue/Black, Black/Blue, Yellow. For the HPFP QCV sensor, it's White, Red. You'll know if you did it incorrectly because it will cause a lot of other codes to appear related to shorts.
