I'm using a 92-95 exhaust manifold wich i have ported to fit my ZC..
Their is a plug on the manifold (o2 sensor if i'm correct) but i can't figure where it should go........????

 

what do you mean where it should go just take your o2 sensor and plug it into that hole im not to sure i understand what you are askin! is there two holes on the header? and you only have one o2 sensor? if so just plug one up!

 

Ok i'll explain better...

I have one plug on the exhausat manifolf (3 wires.. green, white and black) but the connector doesd'not fit anywere on my car!? So i just have to cut the connectoter and wire it to the right place.... but i don't know were... the colors doesn't match........ is it more clear?

 

Use the original O2 sensor that already only has one plug. You're trying to use a 92 style heated O2 sensor with the wrong harness.

 

can u explain a little more......?

 

You will need to unscrew the O2 sensor from the header and plug in your original O2 sensor. 91 and older cars use a one wire O2 sensor while the newer ones use a heated style that have more than one wire.

 

great....... now what does mine should look like? got pic?

 

it should look just like the O2 sensor you have now. Just that it only has one wire running from it. It will thread into the "bung" that is welded on the header. I will try to find a pic

 

and one last thing... does anyone has a pic of the pug that is not use fir a zc swap.... i know there was a topic on that but i just can't find it

 

I don't have a pic, but there is a plug on the back of the plenum that you don't use. It's a two wire plug (male I think).
