If using Holley's 556-112 CNP coils, the Holley 558-318 CNP coil sub-harness is also required (or the Holley 556-128 CNP Big Wire V8 Kit).
For LSx coils, Holley 558-307 CNP main harness plugs into two GM 12579355 CNP sub-harnesses or Holley 558-321 LSx coil sub-harnesses.
If you had a Holley EFI LSx main harness, you wouldn't need the Holley 558-307 CNP main harness or the 558-318 CNP coil sub-harness.

Most people find this document very helpful:

With the Dominator EFI, everything is sold separately. Use Summit Racing's shopping cart for a total price.
May God's grace bless you in the Lord Jesus Christ.

Thank you. Stumbled onto a site that offers a cam sync/crank trigger solution. Just have to contact them with all my questions.

Yes, that's the website. Andy & I are on another forum. Patiently (?) waiting for Andy to log onto the other site and answer my questions. Much appreciate your assistance.
