Thread: Terminator To Sequential MPFI & LSx Coil Packs

    Danny, I'm looking to pull the trigger and make my purchases today. However, I noticed part #558-318, the "Big Wire 12 AWG" CNP harness. Is this just a bigger gauge alternative to the universal harness part #558-307? If so, I think I'll go that route because I've heard the LS truck coils can pull quite a bit of juice, especially if you play with increasing the Dwell Time. Adam

    No! Holley 558-318 is the CNP coil sub-harness for the Holley CNP Smart Coils (not an alternative for the Holley 558-307 CNP main harness). See 2nd paragraph in post #2. Where are you purchasing these Holley EFI parts from?

    You'll spend a little more buying direct from Holley.com. See post #6.
