Location of Connector C300 on 2007+ Tahoe, Escalade, etc..
Does anyone know where connector C300 is located on the 2007+ Tahoe's, Escalade's, Yukon's etc.. I'm trying to track down the cause of my p0449 and p0452 on my truck. I've changed the vent and purge soldnoids as well as the canister and the fuel tank pressure sensor. I have a wiring diagram which shows the wires from the PCM to the vent as well as the ftp sensor and they share a common connector (C300). I tried sending a groud signal from the PCM connector but it didn't make it to the vent solenoid so I know it's a wiring issue somewhere. Any help is appreciated.
