Hard Wiring an Early S197 Mustang to run a Coyote ECU, How To: Coyote Swapped Bullitt

Today we’re going over (again) how we “hard” wire an early S197 Coyote swapped Mustang in order to run an OEM 11-14 ECU. This allows the factory gages, cruise and AC to function like normal and you get a Coyote under the hood all without using a control pack or having two ECUs in play.

I've dreamed of building a 2008 coyote swapped Bullitt with a 5 speed. Very cool build

[@tonsoffun580]

Great stuff. Very informative. Ease up on the language. "Juicy frooting around "😂😂

Another great video .

[@adrb2777]

Thanks for the video. Specifically for the job on the transmission harness pin.

[@MattSoppa]

Thanks for you undying support

I have a 2014 and swapped in a GT harness bc I Roadrunner swapped it. Now, one side marker doesn’t light up, and my hi-beams don’t work. I checked all my wiring, and all of it is in the right spot. The only thing I saw is that the side marker’s wires look like they’ve been repaired. Could that be my issue? How do I check to see if the side marker is getting power/properly grounded? Could that one issue cause multiple issues?

Hard to diag over the internet my friend

Keep up the great work Matt! Where can I go to purchase that Interactive Swap Spread sheet?

[@MattSoppa]

In the description!

[@anthony.james51]

this makes me wanna buy an early s197 and coyote swap it😂 whats the process for doing this to like... a 07 gt500??

[@MattSoppa]

Same process! You'll be able to use that transmission for sure, email if you have any questions

[@DutchStangs_Garage]

Possible to hardwire a Coyote to a 05 V6 (with the 4.0) with that excel spreadsheet?

[@MattSoppa]

Absolutely

[@whpony96]

Does he know that installing the 2018 intake manifold will give him more HP and TQ than the BOSS 302 intake will?

[@MattSoppa]

Probably not but it’s a $200 manifold from ford and it looks better hah
