No, that end of the harness is connected, I need to know where it connects to the firewall.

 

I found this thread that shows that it usually goes off to the passenger side of the motor down towards the transmission.. but still doesn't show the other end.

Also found this pic of the harness

Still haven't seen where it connects to.

 

Found it

 

OK....... Cool.... So that is a view from the bottom of the engine looking up on the bottom of the water pipe on the passenger side of the motor. No wonder I couldn't find it, it's tucked underneith.
Thanks Glex.... Your gooooood!!!!

I'll try to connect it before I drive home tonight and maybe the new engine will act like the old one again...

 

Another angle on it as well

Better yet

 

It doesn't look like you have the sensor plug on the mount from this picture

 

Right, when the old motor came out, I disconnected it which means it's not attached to the hanger but it prolly just hanging back there. I will have to feel around for the black plug and connect it to the blue and then clip to the hanger.

 

Did you plug the connector yet?

Did you feel any difference?

 

Oh, sorry.... Yea, I found it and plugged it up. Yea it made a difference. Little more power and revs better.

Thanks for your help....

 

Good stuff glad you guys got it all figured out.
