i am switching my 89 5.0 from fuel injection to a carb and i need to know what wire (color w/ stripe color) goes to the fuel pump from the computer so i can hook that to a toggle switch or make it so when i turn the key the wire is hot. i am trying to finish this project today so if someone could respond quickly i would love it!

 

after reading this Installing A 1987-93 Mustang SEFI 5 Liter V8/AOD Drive Train into A ’61- 79 F100 - F250 Truck .: Articles i am more confused than EVER!!! can someone just tell me what wires i need to run to power/ground in order to make the fuel pump turn on when i want it to!!!

 

On this document.. http://fordfuelinjection.com/files/eectch97.pdf page 14 and 15 show the computer pin assignments. Pin 22 is probably what you want.

 

just finished, i read that document I posted and saw that it said something about a pink and black wire so i found the inertia switch and spliced a toggled hot wire into the black wire before the inertia switch so that will still kill power to the fuel pump. thanks btw the enertia switch is located just behind the brake pedal.........

ps: you might want to put this into a archive somewhere that the pink wire with the black stripe behind the brake pedal go to the fuel pump for the next person to convert their truck to a carb.

 

Make sure your toggle switch is rated for the full fuel pump current, otherwise it will get hot in a hurry.
