Top swap injector adapter

I'm in the process of getting the rest of my top swap parts together for a 2003 SS, I have most items so far but need a little help to make sure I order the right injector adapters.
I am pretty sure i need the adapters for EV6 harness to EV1 injectors which on ZZP's site would be option C or D. Can any one confirm this for me?
One of the adapters ZZP offers is just a simple plug with no wire and one with, will the both work or is one better than the other?

Yes, you’re correct You need the EV6 harness to EV1 injector adapters which are ZZP option C or D. Both versions will work. The one piece plug with no wire is the simplest clean plug and play solution and is usually preferred if fitment allows. The wired pigtail style is only needed if you require extra length or more flexibility for routing the connectors.
