2019 Silverado Z71-RST ECM Pinout
Can anyone assit with the ECM pinout for the EVAP Vent Solenoid control wire? I'm fighting a P0498 code and have replacee the solenoid and electrical connector and now suspect a wiring issue between the solenoid and the ECM. I located the ECM behind the wheel skirt at the drivers side front wheel. there are 3 large X-connectors, 2 black and the bottom one is blue. Need to idnetify the correct X-connector and pin number for the wire to the solenoid (negative pull-down wire). thanks!
