stroker swap update pictures
Thanks to all of you who have helped with so many suggestions. I am moving along 
The first picture is the wiring harness for the fan that was suggested to me from this site. I was able to get this spliced into the fan harness and the temp sensor plugged in. It's already to go.
You can look at the power steering post on the my other thread to see the spacing suggestion I took from the site to get the power steering mounted.
The second picture is the coil and the map mounting locations that you can see, also suggestions off the site.
So again thanks for all the help and I have more questions coming

Re: stroker swap update pictures
Question relating to the first picture. This fiting hanging down comes off of the original (non tpi) wire harness not far from all the airconditioning attachments. Is this a ground I need to attach to the back of the block? Is it neccesary if I am not using A/C? Would it have attached somewhere else and not be hanging there if I would have pulled the wire around if I was using A/C?
Question relating to the second picture. This attached to the transmission. What is it? Spedo?

First Picture Question: This is the back of the HSR. The top fitting is where I hook up the MAP vacuum hose. The lower fitting that looks the same the book says to attach a vacuum hose to the fuel pressure regulator. Wheres that?
The second picture shows a hose with a fitting that comes off the factory (non tpi, that one is completely off) wiring harness. That went I believe to the fitting on the third picture on the original tpi motor. The top of the picture (the old motor one 3rd picture) is that the fuel pressure regulator. Do I need to buy one for my new motor, rob from the old one. Are all these pictures related or are these two separate things I need to take care off. I am sure someone knows how to identify all this and what to do.

Re: stroker swap update pictures
I don't think I need the EGR. IS that what the fitting from the wiring harness that I have a picture of went to?
Also can I rob the fuel pressure regulator or is it best to buy a new one that I can adjust for the bigger motor/injectors?
