P3690152AB Wiring Harness Kit ground wire short

Thanks for trying, I've already seen that. I see nothing in there about a yellow wire. The thing is, the coil does not require a ground to run. I've no idea where you're at with this.

If you look at the diagram on page 10, the only ground in the entire ignition system is the flange mounts for the ECU itself. The box MUST be grounded.
