I just got one of these and this the question.

I am running a pressure and it is plugged into the rail sensor. THe gauge connection connects here also.

So what plugs in first?

I can figure that the gauge should go first but just want to make sure.

thanks

 

you are correct guage first

 

thanks for the info.

 

On my Commander the rail pressure is a T-tap. The Tap is tapped into the XZT harness at the fuel senor. The stock plug then plugs into the XZT harness.
