take your pick of which electrical manual / year you want per my diy link below

i see what you are doing,, going from a 4cyl to 8cly in an original 4cyl car.

since your looking for the fuel pump and trigger, skim through the evtm(s) and get your head around the fuel pump leads.

the EEC will trigger the EEC relay which in turn will trigger the fuel pump relay.
dont hose it up!!! dont just wing it and start powering stuff,,,,,,,,!!!!!!! that tan / light green wire is ***NOT*** a wire you want to mess with lightly **while** it is hooked up to the eec.
The eec will provide a ground signal to the fuel pump relay via the tan light green wire (same wire that appears on your self test connector up at the driver side strut tower.

if for some odd reason (after you get this part behind you) and you find that your fuel pump runs 100% of the time when you turn the key forward, pls say something!!

the fail safe is the inertia switch in the rear of the car (most of the time along where the driver side tail lamps are).
The fail safe to the NSS based on a stick would be the aod range selector switch, not sure what you have for power train now.,, sorry if you mentioned it and i missed the sentence.

Automatics must be in park to start. Not sure but I think the switch is located at the trans with the gear selector switch.

First: do you NOW have the manual trans in the car, or is still auto?

If that answer is yes, then you need to either hook up the neutral safety NSS, or do as i did, and just jump the two wires (for the life of me, can't remember their color) but if you do this, you WILL be able to start in gear. Use at your own risk!!

If you've still got the auto trans, (which I'm assuming you're manual trans since you went from 2.3 to 5.0, and can't use the TC's A4LD behind a 5.0) then I can't offer a clue.

On my neutral safety, i just stripped the two proper wires, connected them with a butt connector and taped them up. There are better ways to do it in that manner, so when it becomes a priority, I'll redo mine with a harness so I can also have back up lights.....

the neutral safety wire should go through the floor right under the center of the dash, on the drivers side of the trans hump.
There is a connector under the dash on the drivers side behind the heater and radio controls

The question is was it originally a 5 speeder or converted to a 5 speeder from an auto 2.3 TC. If in fact it was an original 5 speeder car it should crank . Crank issues are void of the ECM.

the bird harness if from an 88 will be almost plug and play, you might need to repin some wires.

Oh is there anything else to do with auto-manual nss?

Yes you need to find the NSS switch wires and the reverse wires and wire them correctly. Splice the 2 wires together from the stock NSS switch. And wire the reverse light wires to the New T5 Tranny reverse light switch so the reverse lights work. The 88 harness is so close to the TC setup i would use it.

There's only 2 parts of an '87-93 Mustang wiring..anything that will work on a 5.0 Tbird/Cougar, and they are: injector harness, and T5 harness. Everything else is much different.

dono,, to me its just all sensors, relays and wires and connections. if stuff needs moved around you just gotta muddle through it one step at a time. wire is wire, switches are switches.
