Holley Efi part#s

[HiNoon]

Guys I've looked for an old post that contained all the part#s for a Holley efi install with a 4L80.I'm hoping someone can repost all the numbers bits and cables.I'm using a TCS controller for my 4L80.Worst piece of crap out there.No consumer help when the unit failed twice!Long story save your money.But to get my Ty back up to ramming speed I'm stepping up to a Holley..Any help with the post I can't find would be appreciated. TJ
