4.0 s197 coyote swap wiring.

[Jake Johnson]

Hello, I hope you are all doing well. I have swapped my 2006 mustang that was an auto V6 to a 2014 gen 1 coyote with a Tremec 3650 tranny and an 8.8 rear end. The swap is all done minus a portion of the wiring. I have the Ford Performance gen 1 control pack that came with a new computer and everything needed to run the motor properly. The problem is I now have to splice the computer to the factory harness to give it control. There are about 10 wires that need splicing, however I don't think they are all necessary. The instructions for the kit don't help me. I am only 20 and I'm not experienced with this kind of thing. The instructions are as follows.

Connect the blunt leads as follows:

A. Blunt Lead 1(pin1) – Fuel Pump (Dark Green): Connect to Fuel Pump positive. Separate ground for fuel pump must be provided. The fuel pump will be running any time key is on.

B. Blunt Lead 2(pin5) – Ignition Switch Position (Red/Light Green Wire): Connect this wire to a SINGLE SOURCE on the ignition switch that provides 12 Volts when the key is in the ‘Start’ (cranking) and ‘Run’ position. It is imperative that this circuit be reliable, the PCM will interpret an intermittent voltage on this signal as a request to shut down the engine! (Hint, if your engine shuts down after a hard launch check here first).

C. Blunt Lead 3(pin3)– Starter Motor Request (Red/Light Blue): Connect to start node of ignition switch so that 12 volts is provided when engine starting is requested.*

D. Blunt Lead 5(pin7) - CTO (Tan/Yellow): This wire is the tachometer lead. This is not a mandatory connection.*

I also have wires labeled VSS signal in, VSS signal out, VSS grnd, and 12V key on.

Other wires include the starter solenoid feed and PWR cooling fan with GRD cooling fan.
I'm confident with the fan wires. I just need assistance with the key and starter wiring.

Here are photos of the wires.



My questions are; Is there a list of what color wires on the ignition switch are what? What wires are needed to at least get the car running and out of the garage? And what color wires do these need splicing to? I know you guys have tons more experience then me so any info would be appreciated. I appreciate you reading, Thanks!!

Everything you need to connect should be in the 50 pin C175B connector that used to plug into the V6 PCM.

I appreciate the suggestion! After further investigation I found that the green wire was starter request and a yellow wire with maybe orange stripes was the key on wire. These wires are found right at the steering wheel on the ignition system.

Check out Wiring Diagrams (for connections/wire colors) and Powertrain Control and Emissions Diagnosis for specific intel on how systems work and troubleshooting.

Look up Coyote swaps for other member experiences. Some are likely to share their experiences/answer questions. Just PM them directly. If you really get stuck let us know where you're located; maybe a member is close by who can help.

You've taken on quite the project. Good luck.

Just started a similar project, 2006 V6 auto to 2013 Boss Manual.
Motor installed fairly well after a 2014 K member and EPAS.
Engine came with everything down to the air filter and harness.
The issue we are seeing now is that the main ABS connector will not reach the ABS controller, and the 2013 fuse box/panel will not reach the mounting location.

Did you run into these issues?

I dont have abs.
I only used the engine and trans harness.
So, no.

adjust the routing of the cables.

What exactly is your setup? The stock fusebox should fit where it always fits, and the if the abs loom isn't reaching you might just have to extend it.

Sorry for the delay, we warped a head in another ford and spent the last few months working on that.

For the 2006 V6 to Boss swap we quickly found the the body harness swap is a lost cause. It may work for a 2007 or newer S197, but the harness are too different in 2005 & 2006.

We purchased a PBH harness and now need some experienced help with how to route and connect.

There is no specific routing for it, I ran the interior portion through the firewall under the fender with the actual fusebox under the passenger side footwell, and the ignition wiring/obd2 port behind the radio part of the dash, the length was perfect for this and the rest of the exterior portion of the wiring was just run up towards the headlight to the pcm (Because it was mounted near the stop location). You can tap into the cooling fan pigtail as long as the circuit is still good/the ground for the circuit, you can only really use the high speed portion of it.
