Before doing any cutting or splicing, I need to map out each harness. I'm doing this by creating a spreadsheet with each connector on the harness and using a multimeter finding continuity from pin to pin. It's very tedious, but I want to know what every wire does. That way I have a good plan going forward and remove connectors I don't need.

Shown below is the passenger fender harness from the SN95 mustang. My plan is basically rebuild this harness with the EECV connector. Most of the mustang specific connections will remain. Once I know where all the wires go I start cutting the harness apart. Right now I'm not trying to cut any wires but remove them from their connectors. But it becomes quite a mess and can be overwhelming. But take it one wire at a time and I eventually got the EECV connector separated from the F150 engine bay harness. Right now I'm researching connector terminals. It would be nice to do minimal splices and actually repin the harness. But the EECV terminals are proving difficult to find. I think I have found the terminals for the explorer cam/crank sensor. Also the terminals for the coils. I have ordered the all in one solder and shrink splices to make things easy.

Once my connector spreadsheet is complete I'll also share that.

dleach, did you find compatible plug wires? I ordered 98-02 Camaro LS1 plug wires and they didn't fit onto the spade connector.

Probably going to grab some from the junkyard to try before ordering another set

Hey everyone. Figured I'd share the EEC-IV to EEC-V conversion that I am starting on my SN95 Mustang. While this will also end up on my YouTube channel, some things are better shared in text form.

Why am I converting the Mustang from EEC-IV to EEC-V?

I have several reasons for the swap. One being that the EEC-V supports ODBII, which I then can record data for better analysis of my autocross/track runs. Second, switch the ignition system to distributorless. This is to bring the old 302W into the modern era of ecu control. Plus getting rid of the distributor will clean up the engine bay in my opinion. Lastly, its not a very common swap that I think is more affordable and just as good as the aftermarket options out there.

What parts am I using?

• 2002 F-150 5.4 harness
• 2003 Crown Vic ECU
• Explorer 5.0 Timing Cover
• Explorer 5.0 harmonic dampener with trigger wheel
• Explorer 5.0 cam and crank position sensor

Things left that I need to figure out

• Figure out what connectors need to splice from mustang engine harness
• Figure out how to merge F-150 harness into Mustang body harness
• Figure out what sensors to use from Mustang and which to use from donor vehicles (ie F-150, Crown Vic, etc)

I should have it running before the end of the year. I have so much to do on the truck, It's overwhelming so i lost interest for a bit this summer.

Definitely been there. I have a 4runner that's been sitting waiting on an engine swap.

I'd be interested in see the brackets you come up with. I'm debating trying to do bolt on to valve cover bolts, or welding on bolt pads on top of valve cover, or through bolts on top of valve cover.

I'm in the planning phase right now. I have the engine harness and ECU. The plan is to complete it over winter off season and get it running/tuned early spring. I'm also thinking a bracket on the valve covers is the best option for mounting the coils.

Thanks. Waiting on a 4 to 6 pin MAF adapter, then I'll find out how she runs.

I recently purchased a complete engine and I got the tune with it. I'm still learning all the intricacies of tuning the ecu and going through the tuning documents on the homepage. I don't know anything about the person or company that created the tune. Would someone mind looking over the tune? I doubt there is anything that will cause issues, just looking for a second set of eyes.

I did a bin compare to a stock T4MO and there were quite a bit of changes.

Thanks in advance

Oh perfect. I didn't know that was an option. Thanks.

I'm planning on installing an EEC-V on a Windsor based engine and want to run coil near plug setup. A lot of EEC-V engines were coil on plug. I don't think these coils would survive near the exhaust manifolds. And LSx coils or smart coils are said to not work with Ford ecus.

Are there non smart coils that are Ford compatible that people are using for CNP setups?
