Where is the connector for it?? I am getting a P0135 code and when I put my scan tool on it there is zero activity shown on the circuit. Same scan tool put on 08 Ranger shown oxygen sensor working as it should.

It should be a 4 pin black connector on one end and the other end is in the downpipe just downstream of the turbo. I'm not sure where the 4 pin black connector is but check along the firewall.

I found the connection, it is under a cover, under the floorboard on the passenger side but has 6 pins. What 2 to use to check for 12 volts ??

If it's anything like a normal o2 sensor it should flucuate between positve and 0 during normal use. You have to read it while its in use.
