easy access to O2 sensor wire? - 4/25/2008 6:30:32 PM    northey87 Posts: 757 Joined: 10/17/2007 Status: online Is there a place in the cab I can get to the O2 sensor wire easily? I would like to install an air/fuel ratio gauge and really don't want run wires around and under the truck. _____________________________ '95 1500 Silverado, 350, flowmaster Force II exhuast, S&B CAI.

Through the kick panel, out through the rubber boot where the door wires run, pop out through the bottom of the rubber boot, and go in between the inner and outer guard and drop it own and under the car o the WBO2 sensor. _____________________________ Regards Howard (in reply to RonH) Post #: 3
