Help!!! What else is needed???

Okay I'm buying a mass air conversion kit from summit. It comes with 70 mm mass air a EEC-iv computer and 8 24lb injectors. Thats it for 500 +. So all I need is now the wiring harness to make it all work right? Or do I need the whole engine harness? Im lost Please Help its on its way. O by the way a new short block and the trick flow kit is what im plan on putting these on.

Thats what I thought but no the harness is not included because why, I dont know but thanks b/c summittt sells just the wiring harness for mass air conver.
