hello all,
im trying to put efi from a fox into a 65 mustang 289. i am having trouble finding out the wiring situation, i need to know what sensors and other wiring i do not need from a stock harness and how to properly take them off the harness. also i have heard the firing order is different, how would i go about rearainging the injection setup to the firing order i have. any helpful hints? -

 

look here EFI on Early Mustang

 

the 5.0 h.o puters are like this, not the regular fulies,just wire it the spark plugs wire likr the stock 289 it will run, or u can switch to a 351w cam and have the proper firing order u need to take the gear on the bottom of the stock distributor and put it on the efi one because the two are made of different materails and will get chewed up if u dont. u need to get the efi wiring book form one of the mustang companies

 

so i need to hook up all the wires from the harness to make it work properly? change the distributor also, i already have a 351 cam in the car so i guess that will not be an issue? leignthin the wires and thats it?
