What are you trying to do? Convert to a 4.6? 5.0? Or???

Basically, you will have to swap out the engine harness, all wiring harnesses, and computer. It's much easier, an very straight forward.

ok...yeah...what im doin is a 5.0 swap, i bought the car, all the work is done, but no wire harness or computer...was just wondering if the gear from a crown vic would work!!!

Re: conversion question!!!
 

You may have to rewire somethings, but yeah basically. Just plug and play.

The harness will work, but the computer may or may not. Some of the 5.0 vics were non-HO. The mustang is HO. The way to tell if your engine is an HO engine is by the firing order (HO being 1-3-7-2-6-5-4-8, non-HO being 1-5-4-2-6-3-7-8). You need a computer to match weather it is HO or non-HO. Also, if you are going to be running a mass-air sensor, the engine has to be HO with either a A9L or A9P computer. Check out www.fordfuelinjection.com for more info.

100% Right......

Best too buy a Harness out of another 90 model 5.0 too match the existing Brown or Brown and Grey pugs coming through the firewall on the drivers side bye the brake booster...I am no expert bye no means but have converted 3 myself in the past years...JMO

You will need a harness from another from a 90-92 Ford mustang. Those years are the only ones that will correctly match up to your chassis harness.
