infernosg's S5 N/A Build

[C. Ludwig]

I probably did tell you to ground everything to the engine. After talking with Lance at Pantera EFI, who is kind of the grandfather of these coils used in performance applications, we changed the way we wire the coils to ensure consistent operation. We now take pins D and E directly to the battery.

Yes, 14g mil-spec wire. I'd use 12g if I were using automotive hookup wire.

Maybe my pinout is different but it says pin E is 12V power. I assume you're combining the ECU and battery grounds and keeping the one engine ground? So with the Sprint RE I'd just connect those two to the ECU sensor ground, which goes to the battery and everything should be fine? While on the subject do you recommend following Haltech's recommendation for ECU grounds? That is, one to chassis and the other to battery - (sensor ground). Since I'm rebuilding my harness I might as well make sure I do it right this time.
