Hey John..the paint matched pretty good as far as I could tell.My car is covered and away in the garage for the winter so I could not pull it out in the daylight to check it out.
1- I used an extension and taped the bolt to the socket and was able to get the bolt started that way.It is a pain but it can be done.
2- That plug was for the cmcv connector and is not used anymore.
It took me 16 hours to do mine by myself..have fun
I took it apart the other night and found the problem.You guys were right,part of the sensor harness was caught between the intercooler tubes and the block when I tightened them down.Simple fix and no problems now.Thanks again
