Adding isolator relay under hood of 2017 Chevy 2500 diesel
Can someone tell where under the hood I can find the B+ wire that runs back to the trailer plug on a 2017 Silverado 2500 Duramax? The B+ terminal is currently on always at the plug and needs to be off when the ignition is off to avoid running the truck batteries down. Additionally, is there a best place to connect to an ignition on + wire to power the isolator solenoid? Thank you!
