Im looking for a modern wiring harness to put in my 64 dart. Im running a 5.7 hemi and havent bought anything ECU related either. I know Painless makes a mucsle car wiring harness and LS1 engine related stuff, how good is it? Whos used Painless for there cars with EFI? Im not interested in messing with the programming for the 5.7 Hemi, I just want to plug it in and go.
I used the painless harness for my LT1 conversion a few years ago. THe install was easy, all of the wiring was labelled and the instructions were good. Everything is going good with it in the car for the past few years. Their tech dept was very helpful everytime I have called them. Hope this helps.

I have done few Painless harnesses, And I switched to Detailzone harness about a year ago. They are set up to be super clean under the hood. They install in about the same time but are more money. Check them out. They junction block is kinda large but I can live with taht for a clean as they are under the hood.
I have used them all and keep coming back to the Ron Francis wire kits, they have awesome parts, fit great and are very easy to install. They are all good units so I guess you need to decide what one you can get the best deal on. Good luck
