I'm going to be pulling a EFI 302 to put into my single cab short bed that has a straght six in it im wanting to pull the entire computer and everything else ill need to do a direct drop to have everything stock id like to know exactly what i will need to pull and what i wont need ill pull the trans too the motor is coming out of a 96 explorer it has coil packs as well

 

While what you are attempting is not impossible, it will be extremely difficult going the way you describe & many things WILL get in the way of it successfully running in the end.

To start with & for greatest ease, you will need the complete underhood harness from a 94 5.0 that matches your existing transmission & the computer too. Trying to piece the 300 harness to match the 5.0 and/or the coil packs of the explorer will most surely fail unless you are a really sharp mechanic & have Ford documentation with a lot of electrical know-how to boot.

If you haven't got the 5.0 yet why not just find a 5.8 rather than the Explorer 5.0?

And not to be a hard ***, but punctuation & breaking things up into individual sentences will go a long way to getting help here.

Good luck with your project.

 

Can I not fit the explorer harness into the f-150?

 

I'm not 100% positive, but I'm pretty sure there is not the same options for transmissions between the truck and explorer. So the harness and computer won't run it so you would need a stand alone computer to control the trans.

 

Sorry about the punctuation problem, it was very late and I was in a rush.

 

Are you stuck on the Explorer engine because its free, available, etc? Because its different with the coil packs? More information is needed, cause this has potential money pit/yard art written all over it. No offense intended.

 

I bought the explorer intending on a carbureted build, but I'd rather stay efi. I figured if I pull everything from the explorer I could retro fit it to the f150, and have the computer just think its still an explorer, it will use the explorer trans too.

 

If you source wiring diagrams for the Explorer and the F150 you can make it work. It's not plug-n-play by any means. It would be much easier with a wiring harness from a 1994 F150 with a V8 engine. To get that V8 to fit you need the motor mount brackets and motor mounts from a V8 equipped F series too.

That Explorer uses a GEM module that interfaces to most everything in the truck including the PCM. That adds more complexity to the project. Add a pressure transducer for the fuel tank that the PCM looks at. The list goes on....

 

I see, thanks for the information I will look for a parts truck

 

Man, I commend you for wanting to keep the EFI over the semi-controlled fuel leak...

But that's a lot of work to make something work. What kind of transmissions does the 6 have that makes you want the ex's?

 

I'm not sure I just figured it'd be an easier swap

 

I have someone going to ft worth this weekend to try and pick up a wiring harness for me, now can someone please tell me everything he will need to get so I can drop my explorer motor in my truck

 

As 302's go, the Explorer 5.0 is pretty much top of the heap as design evolution in the Windsor family of engines goes. It also has some unique features that will make this swap less than straightforward. The Explorer is a completely different animal than an F series truck and nothing will be a direct plug in swap. The EFI system is OBDII and uses an ECM that has more pins than the EECIV system used in the 94 F150. Once you get into the OBDII systems, various modules in the vehicle communicate with each other over the vehicle data bus and if all those modules are not present and working, the ECM may not be happy. GEM module was already mentioned and there may be interaction with other cab mounted modules like PATS and PSOM. The ABS module may also be required and I think I should also mention the airbag module. These modules also may be programmed with the VIN, which must match.

It quickly gets to the point where the best approach is to have the entire donor vehicle handy. You pretty much need every piece of wire under the dash and under the hood as well as all the modules. Most of it will be cut up or stripped out and you are going to have to Frankenstein a wiring harness containing the neccessary circuits to transplant into the F150. Be sure to have factory EVTM's on hand for both vehicles and be prepared to spend a lot of hours doing this.

I don't think anyone makes a wiring harness to do this, so you're pretty much on your own.

Another issue is the transmission. I believe all the V8 Explorers were automatic and the 4R70W was used. The ECM controls the transmission and your 6 cylinder F150 will use an E4OD, which will not work with the Explorer ECM. Swapping to the weaker 4R70W from the Explorer is possible.

Using the Explorer engine with F150 engine controls is possible, but the best way to achieve this is to treat the Explorer engine as a long block and use the V8 accessories compatible with your truck. This means getting an ECM with MAF from an F150 that is also compatible with the transmission you plan to use. You will need to replace the Explorer cam position sensor with a distributor and you will lose the EDIS ignition system used on the Explorer. Coil packs and crank sensor will also be removed in favour of the single coil and distributor cap and wires.

I'm not sure, but the fuel pump system on the Explorer may be a PWM style of pressure control instead of the bypass regulator and return line used on the F series. Yet another ECM issue you need to deal with and it may require swapping out fuel pumps and modifying fuel lines.

Just a thought, but some of the early modular motor equipped Crown Vics were EECIV. They had external EDIS modules and 4R70W transmissions. No PATS or GEM modules. I did pull a harness with ECM and EDIS modules out and they look relatively simple. I had exactly this application in mind, but I have not progressed to trying it. Just food for thought.

Good luck with your swap!

 

All this to gain 2 cubic inches???

 

why not just trade the 6 for a 302 5.0 truck, they are out there...I had one...???
