I have an 87 Stang GT 5.0L that was speed density and i swapped it to mass air flow to run a highrise manifold.I need an engine harness for an 89 GT and i'm trying to clean up the engine bay by hiding the harness in the fire wall somehow.So i need a longer harness to do that if anyone has done that or knows what i'm talking about it would help if someone could shoot me a part number or something. thanks
