    The main thing I need to get straight before I start is the wiring harness.does the wiring harness with pcm come out?I see where some of the cables with big connectors are on the drivers side just below the strut mount (I assume that gets disconnected) there are Also two wiring harnesses going to the bottom off the fuse box , does the fuse box come out or can those be disconnected) if someone can give me a quick run Down with the wire harness for engine removal that would be great.

    Is it better to bring the whole main wiring harness/pcm out with car or leave it in?

    The majority of the electrical should come out with the cradle. The fuse box separates. Gently pry the tabs around the sides and the top will separate from the bottom. Flip it over and you will see three large square connections with a bolt through each one. Undo the bolt, and pull the connections out. Two will go with the cradle out of the car, one will remain.

    The big connector on the driver strut tower needs unconnected as it will come out as well. Pull the pcm out of the airbox and flop it on top of the engine when removing/installing the cradle.

    Ok thanks,I wasn't trying to separate the engine tranny if I don't have to, is there any other way to hold the crankshaft from turning when trying to get the damper nut off besides the fly wheel?

    Feed a piece of soft cotton clothes line into one of the cylinders then rotate the engine around by hand until the rope compresses up against the head. the engine is essentially locked up at that point and you can unbolt the harmonic dampener. Make sure you rotate the engine counter clockwise when locking it up, and leave enough rope sticking out to pull it out later. Of course since your removing the heads the second part doesn't really matter.

    You can put a tool on the flexplate teeth, they sell one that bolts to starter mount hole. Most have rigged something up though.

    I also heard you can use a strap wrench or chain wrench with a leather belt around the damper? Yea that's the tool they use in the fsm on the fly wheel , so any part store should sell that tool?

    Careful, the damper bolt takes A LOT of force to break loose. Check eBay for the flywheel holder j tool, you may find someone parting with one for cheap.

    I don't think all data has out the top instructions. Basically, you would remove the exhaust y pipe, ALL the trans to engine braces and unhook all the engine electrical since it will be staying with the body. I think you need to remove the balancer before pulling the engine, otherwise there isn't enough room to get the engine off of the trans alignment pins when separating.

    I think the crossover has to come out to separate from the trans.
    I would take rad/condenser out to keep them from getting damaged even if you didn't have to. Too easy to dork em up.

    Thanks and I can access the fly wheel and torque convertor bolts where the starter goes or do I take the cover off at the bottom to get to those bolts?
