Hello! I've been reading this forum and getting useful info here for a bit, but just recently joined so I could ask this knowledgeable community a few questions!

Has anyone ever done an engine swap using a 94-95 mustang GT 5.0 as a donor? I just so happen to have a 95 mustang GT with a 5 speed and am planning on dropping the engine into a bronco. My question is, how much of the wiring harness will I need to keep? Obviously, I've pulled the engine computer (EEC) and complete harness from under the hood. Is there anything under the dash that I can't run this engine without?

Thanks!

 

I'm pretty sure that era stang had the 4.6 in it. The old 5.0 was the push rod "302". The new 5.0 is a completely different engine.

If it's a Bronco from the late 80's to around the early 90's or older, the old push rod 302 should drop right in, since they came stock with them.

Really, you can put any engine into any vehicle... Just depends on how much time and money you have..

Good luck!

If you do go through with pay attention to the firing order of the cylinders there's a possibility the the stang 302 might have a different firing order than the bronco 302

 

Nope push rod 5.0 was still used

 

Yep, sure enough on the old 5.0... Got confused when the 4.6 actually came out (around 1991), but it didn't end up in the Stang until around 1996...

mustang didnt go modular until 1996. It could swap but there could also be compatibility issues..

 

I think you're both right. The 4.6L was introduced with the new body style in '94, but only as the standard V8. The GT retained the 5.0 for '94 and '95.

Anyhow, as I mentioned, I have the 5.0 (pushrod 302) sitting on an engine stand ready to be dumped (okay, mounted!) into a 1971 bronco. The original engine is the 302, so the engine mounts will work without modification. A huge benefit!

My question regards the wiring harness. I've pulled the entire harness from under the hood, including the EEC, CCRM, and power distribution module. Do I need anything from under the dash to make it run? I've still got the mustang, but want to be sure I don't need anything else (like maybe the instrument panel?) before I recycle it.

 

I would find someone who's done the swap. It's doable for sure just a mater of wiring it up. All you really need is an EEC I would think. I've seen lots of old mustang that have done the simular swap.

 

Yeah, I'm pretty sure I've got everything I'll need to get the engine running, since I've got the donor mustang still. I just wanted to avoid the pain of pulling wires from underneath the dash and God knows where else in that mustang if I don't have to!

One other challenge I know I'll have is adapting the T5 manual tranny to the dana 20 t-case. Apparently, Advance Adapters used to make such an adapter, but no longer supplies it. I've a mind to make my own, though if I could find a used adapter from somebody I'd be willing to pay a few hundred to save myself the hassle of fabricating one.
