Help with stock EFI

I just pulled a 360 magnum out of a half ton truck today to put in my son’s 67 Dart and I would like to use the stock EFI for now. I pulled the computer and I have the wiring harness all the way to the fuse box. Do I need the fuse box and more of the wiring including the OBD II port? Any advice, pictures, diagrams, links, etc would be greatly appreciated. I’ve got 2 months to get the motor, an A518 tranny, complete disc brake suspension, and 8.8 Ford rearend with disc brakes installed and working before my son’s graduation. No problem, right? Lol
I got help with my wiring but glad we Kept OBDII port, it will help later. Grab the fuel pump from the donor, you may decide to use it later. Consider how to provide fuel, you can do a Tanks Inc. tank or fuel cell in trunk with stock pump. Also consider grabbing the instrument panel and wiring for it from donor, some have used it.
