hey guys could really use some help.
So I took the car into a “reputable shop” for my header install. They took the entire day with my car and the shop owner stayed working on my car till about 9pm smh. When I arrived to pick up my car he explained that stainless works gave us the wrong connectors and that he couldn’t plug in the 02 sensors obviously since that’s what the extensions are for
Chugged the car home that night and put her away. There’s a mild vibration in my clutch pedal now that was not obviously there my car has 10k miles

So this morning I lifted the car to get under and investigate what really was going on and if this guys was just having a brain fart and didn’t want to deal with the car anymore. The rear o2 sensors were are installed in the mid pipe but just left hanging there
does anyone have a manual with some picture locations on where these plugs should go.
i searched everywhere for a schematic on the cars plug location, but all I seem to find with that search is the o2 plug locations.

So is this these two here
Sorry, man excuse the stupidity. It’s just these are pointing forward towards the front of the car.
if these are the plugs, obviously I can just pull the push pins from where they are mounted to and set them

The ones in your pic and mine near the transmission crossmember are the rear or mid-pipe sensors. My rear o2 sensors have factory blue heat sleeves on them which is how I distinguish rears from the front. The rear sensors wires are also shorter than the front. I hope that helps.

Right on !
thank you for the help
Very much appreciated
This lazy bastard just wanted to be done for the night
So then the rears don’t need any extension is that right ? These plugs mounted to the side of the transmission with the push pins in my pics plugged right in to the rear blue o2 sensors
