Big thing about returning to FI is finding out why a carb was out on to begin with. If the PO did it right and used a Carb specific cam then you need to split the case and replace the FI compatable cam. If (like in my case) the PO had an engine fire the cam is O.K. but all the wiring needs to be replaced.

First find out what isn't OEM, see if the PO soldered in solid core house wiring (like mine) or used the stock wiring with some sort of adaptors. If the stock wiring is intack up to the relay board then it isn't too bad. In my case I had to rewire the 14 pin plug, the ignition: battery to switch to coil, the starter circut, fuel pump, and most of the wires under the dash (PO used masking tape to cover up some radio wire splices). So in my case it took a LONG time to track everything down.

BTW don't even think about it if you have trouble reading wiring diagrams like I did when I started.

Physically putting it all together is easy, there are plenty of wiring diagrams, vac hose diagrams (thanks DD), and troubleshooting articles on the net. You just need a good base to start from, if a PO starting hacking wires you are pretty much on your own.
