Can someone tell me how the connector for the oil pressure switch on the oil filter housing releases (red arrow in pic)? I can't get it to budge, and don't want to break the connector.

 

There's a lock on it (red tab), you have to slide it to the side before pressing on the tab to take it off like a normal connector.

 

Thanks! It looks like the switch is on far side of the connector when looking down from the top. What a pain. Of course, it's made worse by all the oil that's been leaking from the oil filter housing.

I removed the fender liner and the strut, and disconnected the cooling lines from the oil cooler, and plan to pull the assembly out through the wheel well if I can ever find the bolts that hold the oil filter housing to the block.

 

Clean first, some good degreaser spray…
One of those small mirrors or scope cameras could also help.
