1. Suggest that you get a relay for under the dash and run your ignition off of it, because your ignition switch probably won't last otherwise. I presume that your old ignition wire is not "ballast" wire, which will not work with FI.
2. An in tank fuel pump is preferable, but may not be possible. I got an external pump from Summit that does well. You will need a return fuel line to the tank, suggest you use the original fuel line as a return and run a new fuel feed line.
3. As stated, you will need a constant source of power to the ECM. I connected mine to the positive battery connection on the starter.
4. I would stay with the 92 wiring harness and shorten and lengthen as necessary. Solder and shrink tape all connections or you will be driven crazy when a crimped lead starts breaking down.
