physical wiring layout location
99 Vette Cpe 6MN, looking for physical wire layout of vehicle. I have a fuel tank pressure sensor (Near the fuel fill spout) that is not getting power (5V +) to it and tests indicate a broken wire somewhere between the PCM and the sensor. Replacing the wire seems very time consuming at 1st glance. Hoping someone could show the wiring in a chance I could isolate the wire break and repair at that point.

It's a grey wire at Connector 1 pin 46 on the PCM. Goes thru 2 connectors before it gets to the sensor. Not sure where those connectors are. Looks like the ground has the same path from the PCM as well. Hope this helps some.
Found some connector info..
C142 (20 cavities)
Engine harness to transmission harness, RH side rear of engine compartment, below the battery
C402 (10 cavities)
Transmission harness to fuel tank jumper harness,
