P0134, 0135 & 0155 after O2 sensor replacement
Got these 3 codes & a Check Engine light (not flashing) after an engine install, so I replaced all 4 O2 sensors and still get the same codes. After reading a couple other posts, I don't believe the parts from AB were defective. I can clear them with my UG, but they come right back. Truck runs great...no symptoms. Any suggestions???

OK, so unplugged all 4 for cleaning. I noticed that the front Dr Side one, the female plug (the one that goes to the ECU) has only 3 gold prongs:
I also noticed the one on the passenger side has 4:
The one with 3 does not appear to have one prong broken off. It looks like that's the way it's suppose to be but I'm not sure. I did check the old O2 sensor to see if the plug had a prong stuck in it or something, but it's clean.
So, can anyone verify how many prongs the front Dr Side plug (to ECU) has?
If it's suppose to be 4, could this throw all 3 of these trouble codes?
