MKiV Coyote Gen 2 wiring - Best build thread to read?

[Alex_V]

First off, there are alot of well documented, and simply awesome build threads on here. So this is more about electrical. My next big thing is wiring up a 2017 Mustang GT Gen II motor to Rick's harness, and Ford power pack stuff. Doing electrical is my least comfortable area or this project. Closely followed by paint.


Could anyone recommend a most picture full + noob friendly build thread where wiring a Gen II Coyote MKiV is closely documented?

Thanks

Alex

Paul's 20th Anniversary Roadster thread is the bible for Gen II Coyote wiring. Great photos and descriptions. He also has a link to a spreadsheet for his wiring schematic. It's a little past the actual wiring section in the thread if I remember.

Thanks Steve. Lots of people have used the information in that thread. Mine is still going strong! One caveat: That was an early version of the Gen 2. Ford made a few changes that don't show there. (1) Now has only one clutch switch instead of two. (2) Eliminated the vent line from the CMCV motors to the intake. Now they vent to atmosphere so nothing to do except hook up the vacuum. (3) They integrated the MIL into a bracket with the ODB2 connector. Before it was loose. So as long as you're Ok with the MIL being wherever you locate the ODB2 connector, nothing to do there either. Summary: The later version is a little easier to install.

Yeah, I have peaked at Pauls thread on a number of occasions. Everything is well documented indeed. I struggle understanding the wiring portion of your build thread. I think it's because you are writing from a perspective of someone with electrical knowledge and understanding. Unfortunately I am approaching this from a complete idiot perspective. So information gets lost in translation. For example, I understood (1), No idea what CMCV is in (2), MIL in ODB3 is referred to a red light I think in (3).

I knew wiring is going to be a struggle ))

Yeah, lots of terms and acronyms. CMCV = Charge Motion Control Valves. A system Ford has in the intake manifold. Requires a vacuum connection to function. No big deal, just has to be plumbed. MIL = Multifunction Indicator Light, aka check engine light. ODB = On-board Diagnostics. What all modern cars have to self-diagnose and report. Google is your friend for stuff like this. Not going to sugarcoat it. You're going to have to roll up your sleeves and dig into this. Study the Factory Five Coyote installation instructions. Study the Ford Performance installation instructions. Dive into my build thread (and others) and hopefully you'll see how it all fits together. The spreadsheet Steve mentioned is actual point-to-point wiring directions. But strongly suggest understanding the concept behind. Not just hooking wires together. There's no one way to do this. But what I did works. No easy button here. But honestly it's not that hard if you're willing to make the effort. We're here to help when you get into it. Good luck.

If it makes you feel any better, I had no automotive wiring experience either. It was hard for me to read the instructions with understanding. It got easier when I had the wiring harness and components in my hands. Much easier to follow Paul's thread when you are actually laying the parts out and walking the wires around to where they connect. Label pieces, look at the Ford diagrams, Google Ford acronyms and ask questions. You'll get through it. My car runs and I even know how to use the basic functions of a multimeter now.
