Default Questions

1.) The O2 sensor clips are color coordinated. Which color is the front clip? Grey or black?

2.) The instructions I see for catch cans mention connecting the valley plate connection to the catch can and then to the stock intake. I am not running a stock intake manifold or stock intake. Is the hose that goes from the valve cover to the intake before the throttle body just a pressure relief? Should I tie that into my catch can or what service does do? Should be put a fitting in whatever intake I run to get the same setup?

Sorry, I can't answer any of your questions, but I have one of my own. Have you found a good tuner in the valley?

I am having GPI sending me a remote start tune. They built the motor. I am probably either going to rent a dump and have either GPI or Pray Performance remote tune.

I wish I would have taken a few more pictures before I tore it apart of these vaccum lines.

I think the connector on the driver side valve cover goes to the intake connector. The line I see for the passenger side leads me to believe it connects to the top of the accumulator tank. I am not running stock valve covers do just trying to figure that out.

Well I have a 2014 Z51 with an Edelbrock supercharger, so if I can help with pictures of something let me know.

Do you need a stock pic? If so, which C7, specifically?

I am attaching a picture below. I believe I have it right. I am not running everything stock so my connections maybe a little different but same routing.

Orange- Overflow to top of radiator and top of thermostat housing.
Green- This is the EVAP solenoid, I am going to route this into the vacuum block on the back of my intake but that is the plumbing to the solenoid.
Purple- I believe the stock plumbing from the driver valve cover was to a fitting on the intake, I have one on my new one and plan to keep it this way.
Red Line- This is going to be my catch can. The fitting from the valley cover to the catch can and then to the vacuum block on the back on the intake.
Yellow- This is what kind of fit from a piece I had. One side of the the oil accumulator to the passenger side valve cover.

The red circle is the one I am not sure about. Also, am I missing anything else?

Also, there are two ground style ring terminals. I already have my power on the starter but wanted to confirm. Do these just ground to the block? Thanks. It has been apart for almost a year and it is 117 in my garage.
