After putting the intake back on I noticed a blue electrical connector at the rear of the drivers side head. What`s that for? I don`t remember unpluging anything! Off course, I started this H/C project back in July off last year so I probably just forgot something!

 

probably for the knock sensors

 

Those are undernieth the valley cover. I didn`t take that off.

 

Could it be the oil pressure sensor? And the big question is, can I get it plugged back in with the intake on!?

 

Any other ideas?

 

I think I know what you're talking about.Yeah you can plug it back in with the intake on. I remember a bracket back there with a plug on it that was just held on by a clip. It's a small round plug(don't remember if it was blue),right? I just took a look at my car but couldn't see back there because of the egr tube but I think thats what your looking for. I'd pull the coil packs,bracket, and egr tube to get a clear shot but I know it's back there. Maybe you can just pull the egr and feel around back there. Hope this helps.

 

MAP sensor comes from the passengers side...

Knock sensors and AIR system vavle on the passengers side.

 

Thanks for the reply Ssmoken. I`ve been feeling around back there but can`t find anything! I don`t have the EGR in the way `cause my car is an `02. I feel like an ***!

 

I believe that connector hooks in around that round black valve thing that's hooked into the rubber AIR tubes at the rear of the drivers side head...somewhere. I know it's in that area somewhere I can't remember exactly where...my car doesn't have that plug(98 model)...I remember it from a recent cylinder head R&R I just did on an 02 model.

 

Oops! Did I say egr? I meant air tube. I'm going to agree with "Dustin Butts" on the location.

 

also..feel around behind the intake for a connector that might be hanging down by it's wires. I'm sorry I can't remember the exact location. I just remember a blue connector that took me a minute to find where it went.

 

Well...I am an ***. I found it. It was the connector for the oil pressure sensor. The pig tail for it fell behind the block when I was putting the intake on. I felt around until I found it and plugged it in. The sad thing is, I eat, sleep and breathe this stuff and it never struck a cord `till I found the pig tail. Thanks to all for the help.
