Ok Help! The wiring harness in front of the plenum has a groundwire on the left side which comes off near the Map sensor plug and fuel injector. Where does it go? I totally forget...lol

Let me know...Thanks!

Does it have a round grommet, about 5/8 in size? If so, this will connect to one of the ICM bracket bolts. One of those bolts should have an extra nut on it. If not, then remove the bolt, insert it through the grommet and then into the cylinder head and tighten.

Yup, if it is like Mike described then that is the ground that goes to the bolt that is right under the ICM.
Here is a pic of right where the area is, sorry it is a bit blurry, and you cannot see the actual bolt, but it is right up under the ICM.

Here'* a better shot... circled in red is the bolt the grommet needs to go on....

Yep that'* it! It has the grommet. Thank you...I couldn't remember even disconnecting it...lol

Fuel injector/fuel regulator and alternator to go, along with the wiring harness and throttle body linkage and I should be all set. I plan to do a thorough flush of the engine and also change the oil filter/oil. I need to fish for a 15mm socket and small screw driver that fell victim to my clumsiness I am having a hell of a time finding them so fingers crossed when it is jacked up I will have more success! Thank you for your speedy replies...I hope to finish up tomorrow nite!

Much better shot of it Mike!
I looked over the pics I had and that one was the best I could find, if it was not raining out I would have went and took a pic of the actual bolt.


Hope all goes well with finishing it all up tonight.

Yet another question...I want to add a Prestone flush kit to the car. Which hose is the inlet hose for the heater core? The larger diameter or smaller diameter hose? My common sense tells me the larger...but I want to be sure! Thanks...

The larger one is the inlet, you are correct.

Well guys I messed up tonight. I didn't think I was tightening the coolant drain plug too tight, but the plastic nut sheered off the plastic bolt. Any suggestions on getting the thing out ?

Also is there a particular procedure I need to go through when I crank this thing over? I figure I will be ready soon! Thanks!

Sorry to hear that broke on you, I'm not sure how you'd get it out, but I found the part for you if you can get it out, there has to be some way, good luck!
