Found out today that the computer that comes with the Ford performance crate motor/trans package is not the same case as the ones used if pulled from a donor. So, I had to make a mount. I used the FFR mount that usually goes on the oil pan studs, and ran it across the frame 1” x brace tubes. Tapped the tubes to mount it. The. Drilled and tapped for the computer. I had to shift it pretty good to passenger side to clear the steering motor and help keep the harness from getting into the main pulley. Worked out great. Also mounted the compressor and started working on a trans mount (but will not post photos of that until I get it finished and ensure it works, probably a couple weeks.

Won’t be much for updates. My next days off i have to prep both cars for a car show, then once home, I’m taking the body off and have to pull the motor and trans to fix a couple items. While it’s out and i have room, I will cut the FFR trans mounts off the frame then finish the 6R80 mount once I get it all back together. Then I’ll start working on wiring and towards getting it to life. It’ll be easier with body off and I have some things I wanna do to the body while it’s off.

That's the last place I would have though to put it. Aren't you worried about moisture and heat?

That’s actually where FFR mounts it also. In mustangs, it is also under the hood right next to the passenger side head. So here there is more airflow than in stock mustang. The plugs should all be well sealed as designed. And, the car will see only minimal use when it may rain. So, in short, not really. While i won’t go driving through foot deep standing water, it should be ok for a little incidental wetting.

My son's Fox body and my SN95 are both behind the passenger side kick panel. I did not know that any Mustang had the ECU under the hood.

Yes. After I posted I researched and found that after 2010 it moved under the hood. Never too late to learn, which I seem to do daily. I still think I will plan on putting the ECU under the dash or maybe even in the trunk.

I'm also planning to use the electric brake booster and thinking I will mount that on the firewall in the engine compartment along with the remote reservoirs. All this could necessitate building my own wiring harness which I am also considering.

Since I'm retired I have a lot more time than money. One of the reasons for considering a build is to fill time and have some fun. I spent my entire career designing and building complex oilfield servicing equipment and love the planning process and trying to consider all possible problems before the build. Another reason is to enjoy the drive after the build, but the build is the main reason.

Keep the posts coming and I'll keep learning.

I, too, like the planning and building. People ask when I’ll finish and I honestly can’t say. That just means I’ll be done. Enjoying it when done is fun too but I always looking at what’s next.

As far as the placement, if using a coyote, the harness puts the ecu plugs at the front of the motor. You can move it within reason but to the back isn’t much of an option. The black box mounts under the dash and isn’t sealed. It is where +12 from battery supplies to and the key connects to and all.

Building your own harness is an option, but finding all the proprietary plugs may be a nightmare. Unless you purchase the controls pack, depin everything and start over. But, you save no money, add tons of time and if you don’t get it back exactly perfect, it won’t work, or, st worst, could crater your motor.

I did consider mounting it up higher, more along the lines of where stock mustangs have them. But elected not to as I will probably be running side paneless. Which means I’m trying to keep the under hood as clean and clutter free as possible.

We placed it under the engine as in the manual and we will be fabricating a shield to protect it from debris and other items. When we have it setup I will post a photo.

I downloaded the installation instructions for the control package and admit that the instructions say to mount it under the hood. I will really need to look at this as I don't want to place it down low. I'm not too worried about engine room clutter as I will be using side panels with some sort of venting which I will work on at a later date. From most of the pictures I've seen the Coyote sits close to the firewall and leaves limited space for mounting equipment. Maybe I need to combine an ECU mount into the hood stiffener that is so often added to keep the hood straight.

When I mentioned building my own wiring harness I wasn't thinking about the control package harness. It is my understanding that the ECU that comes in the control pack kit is needed to avoid PATS issues and allow the use of a return type fuel system. I was thinking that the wires could be extended using "jumpers" made with Weather-Pack or Metri-Pack connectors.

I will need to really think on this for awhile.

Your idea of mounting like that in the front should work. The harness ends are long enough to reach from the motor top to the bottom so figure coming off the front passenger head, you’ve got about 1.5-2ft of harness to reach wherever you want without having to modify.

Cool. That solves that problem. Only about 9,999 to go.:smile2:

Prototype 6R80 trans mount. When I pull the motor out (hopefully next week), I will cut off the FFR trans mounts from the frame. Then I’ll set motor back in, get the angle right and trim the long edge of the crossmember, leaving some as a gusset.

After I see how it goes in again, I may weld the crossbmember in then cut out the center and leave tabs on the frame. Then make another plate that is a removable crossmember. I don’t think it’ll be necessary though, since the mount is on the back of the trans case instead of bottom. The flange will have to be up and above the crossmember when going in before it reaches it anyway. Once I’m sure of that, I’ll decide weather to make the crossmember removable or not. Worst case, I cut it out later, remake it to mount from the bottom and use spacers to her back up to right angle.

This is the back


Front. The two empty holes is where it bolts to the trans. The line is just a reference. I’ll trim off even with bottom of frame tubing once I know exactly wheee it has to go to get angle correct.

Brought it to a car show today. She won best under construction. Was kinda unfair as I think it was the only true under construction lol. The mk4 won best 1950-1980, which I was flattered by. There was some nice cars including a very trick, very custom 68 Camaro that won best in show.

Blew it apart partially today. Body off, motor and trans out. Have to put starter index plate in, correct trans bolts and put a couple quarts of fluid in the converter. Cut the factory trans mounts off the frame and then reinstall the motor tomorrow probably. Then I’ll start wiring and mechanical stuff towards running it. The body won’t go back on for awhile.

Got up today and got the starter index plate in, filled the converter, bolted all that back up. Then started in the trans mount. Cut the FFR brackets off the frame using sawzall and cut off wheels. Ground it smooth. Back in with the motor and trans. Then installed the new trans mount I made. Everything lined up perfectly down the center. Welded in the mount best I could. I’m going to have to clean up some welds once trans is out of the way for paint. Got me a perfect 3* angle on the motor checking at a couple diff places. I may add a gusset on the mount towards the back where it doesn’t touch the frame anywhere to add a little strength to it.

Turning big metal into shavings.



Motor back in, supporting and setting angle. Bolted bracket on trans then adding mount and crossmember to that




Everything in place, angles and alignment triple checked and started welding. Can’t really see some welds. Don’t criticize to bad. I’m not a great welder in tight spots. This will fix when trans out again. You can see my centerline marks in frame bottom in last pic.

Worked on the ac and heater lines inside the car today, since I had some underage help. Had to do something that isn’t much thought lol.

Decided to do it next to the riser like FFR. About the best option to keep the hoses easily hideable inside.



Completed hoses. Gonna clean up the trimmed parts of ac inlet box when totally apart for finishing


Had the cutest little helper today. She likes using the drill


The kids seem to lose interest when there’s is work and not much visible progress. They like to see big parts come together. So when she gave up and went to blow bubbles and chase lizards, I started on the second part of the harness for the coyote. The motor harness came installed. After a couple false starts, I ran it down the right side of the oil pan to the ecu. The black box is under the ac unit. The harness to the CEL, gas pedal, etc will go across to that area. And I have to decide how to get the harness into the dash area, weather through the firewall or trans tunnel will work best. That’ll be next weeks work.



I’ve got some learning to do. I thought the ecu had an input from the shifter (comes with kit). But it doesn’t. The shifter has a plug that has inputs to control when you can put it in gear, and lights, but the ecu doesn’t need anything from it. It must get its gear info from the big plug on the trans. That means that I don’t really have to use the ford shifter. I was playing with ideas how to make it fit and match, being its sort of big and bulky, but now I don’t think that is necessary. I’d much rather use a lokar floor mount or something if the sort if I can make it work. I may need to call the tech line and ask a few questions to see what my options are.

Great to see your kids helping, they will be boasting later that they build it!!
That’s perfectly ok with me lol. I’m glad they are coming out also. Admittedly the baby girl is doing more than the boys. She’s got more mechanical ability than them lol. But they have to get her iPad working (and mine for that matter lol!). I think the baby (turned 1 yesterday) is going to be the car builder though. Even at 1, he is looking at how things move and work when he destroys them.....

Actually, he has a new set of wheels y’all might like too!

I "hate" to say this, but he looks like he'll be a great mechanical engineer. I'm speaking from personal experience. :wink2:

My daughter used to come out and help me in the garage when she was young. Unfortunately she became an environmental geologist. :surprise: Oh well!
