After replacing sensor pigtails on the cam sensor and high-pressure fuel rail sensor, all of the sensors are coding?

Replaced pigtails on the cam sensor and high-pressure fuel rail sensor and now all the sensors are coding. Did I cross a wire by accident?

Hello,
Both of these sensors share a 5V supply and ground.
It is important to get the pin location correct.
Please see image below regarding the wiring colors and pins
Hope this helps.
Cheers, Boris

Replaced wiring to diagram specs and erased codes and still codes keep coming back.
P3193, p0343, p0113, p0118, p2539, p0180, p1098.
Did some reading and saw a few other stories like mine but no solutions.
Before this had a code 2177 lean code.
Thinking fuel injector wiring harness might have a short, don't know what to do. Need help please.
