Is pin 54 fuel level signal, and is it black?

On mine, pin 54 is black, but the schematic I have (non GM) says purple. Can someone verify?

 

Both of my non GM pin outs also say purple, if it is the fuel level input wire it should go to blue connector 230 pin J. Check the color there/trace it/ or check it for continuity. If it goes to C230 pin J mabey that ran out of purple wire and used black?

 

Where is blue connector 230?

 

It is one of the 2 dashboard connectors, they go to the part of the harness that goes into the car. It also has the MIL light wire and serial data OBD II wire on it. I am not sure where it is actually located in the engine compartment though, I never worked on a camaro

 

Thanks for the help... I was looking at it, but didn't know that was the one. The wire was purple. Problem was the loose nut behind the wheel

It all works now
