"Anyone from GJ within this route?" Looks like you are planning to go right past me near Vegas, welcome to stop and/or spend the night if that fits your plans!

Earlier you commented on the weight of Eco2 "For some reason I find weights interesting. Total weight, front to back bias . . This is complete rolling chassis for Eco 2. 2389 lbs. Hoping for curb weight to be 4000 lbs or less." Well the 2015 F150 with 3.5L Eco runs 0-60 in 5.8 seconds and...

TW, I have always been impressed with your work here on the GJ, but after having the opportunity to spend 2 days working with you on Eco2, I am way beyond impressed! Your fabrication skills and attention to details are just amazing! Awesome job, can not wait to see Eco2 finished!

Well, the 2015 Ford F150 Wiring Diagrams Manual arrived today, and it is a good thing I waited for it. Just as I suspected, a lot of the wiring has changed from the 2011-2014 system. The PCM pin-out is completely different. The PATS wiring is revised and I suspect the PATS system is different...

Yesterday I got a few hours to work on Eco 2 wiring. This is the dash harness, 14401, with all the mounting clips and all the sleeving removed. I have marked a few connectors with blue masking tape which meas those connectors are going to stay while a lot of others are going to be cut off and...

TW, Just FYI, I am leaving the factory cluster wiring in-place initially. When I come to verify the wiring, I will bring a F150 Cluster so that we can verify that all the cluster display items are working correctly. Then, if you are converting to another cluster, we can modify the wiring...

"What about the brake/shift interlock? Is that switch there or will I need to buy one? I guess we could disable that feature in the shifter itself. I am most likely going to have to build my own fuel tank. No much luck in finding one that will fit. What all will I need to have on tank, other...

TW, Looking at your new floor shifter, I guess we should keep Tap UP/DN shift function in the wiring. What is T/S switch? 2011 had Tow/Haul switch which cancelled OD. Walt

I started the second of the 3 three harnesses for Eco 2 today. This is the dash harness, 14401. I followed the same process as with the first harness. First I cut off all the mounting clips that were on the harness, then I cut off all the sleeving from the main body of the harness. So it...

Today's left-overs. A lot of extra wire that I may use for something somewhere on Eco 2.

Tomorrow I will start on the dash harness 14401. That is a far more complicated harness, with about 30 connectors, but my process will be the same. In 14401 we only need the ignition switch, the cluster, trans shifter, and the OBDII port, but it contains a lot of interconnects that I will need...

5. when you get to the other end of the harness there is a large black 34-pin connector, this is what connects 14405 to the engine compartment harness 12A581. I took the connector apart and removed the wires that I did not want, which requires some special tools. You can just cut off those...

3. Now find the connectors for the components that you want to keep and use. In our case that is the Fuel pump driver module (Black 8-pin connector), the fuel pump and sender connector (Gary 4-pin connector), and the Fuel Tank Pressure sensor (Black 3-pin connector). Find those connectors and...

OK, today I stripped out one of three harnesses that re needed for Eco 2. I started with the easy one, 14405, which is the chassis harness that runs from left side of engine compartment to the back of the truck, it runs right along the driver's side frame rail. 14405 contains the fuel pump...

TW, Hope you are feeling better! Some bad flu has been going around here as well.

Me? No I am retired, from Ford Motor after 32+ years, most of which I sent in Powertrain Electronics including Control System Design and PCM design. I see the recent PCM systems as puzzles that I like to solve to allow people to install late-model Ford Powertrains into older Ford cars and...

Thanks for responding! Will take all the help I can get! Well, 12A581 comes through the firewall and connects to the 14401, and yes there are a ton of things that the 14401 connects to, most of which we will not need. We are going to keep the Cluster, the ignition wiring, and the trans...

And finally, if you add in the dash harness (14401) it would fit about like this, and the black module on the far right is the BCM (body control module) which connects to both the 14429 and 14401 harnesses. and the 14401 also connect directly to the 14429 engine harness. As a next step I will...

Now if I add the Chassis harness, it connects on the far left and runs towards the back of the truck, or in this case, into my living room floor. and as you can see that 14405 harness is really long, like 16 feet! It really helps to have an empty house available it you want to lay out some...

So, moving the 12A581 harness to my dinning room floor, just pretend the blue tape is the truck's firewall. The big lump in the middle just below my fan is the fuse box. It mounts just in front of the radiator.
