I have more of a question actually....

I have just baught a Stage 1 screamin eagle kit from a freind that include everything but the heads, and EFI tuner kit. My bike is a 02 Road King Classic w/ an 88 F.i.. I have an older screamin eagle EFI race tuner with out a disk or adapter cables which im sure is of no use to me, but im still wondering if it might be of any use to me. when i called the Harley shop, they were able to tell me that it is applicable for my bike but if its married to another one its no good for mine. So how do i find out if it is and where can i get another one? Also, im not real sure i have every thing i need for my kit, does any one know any info that could help me out? my email is aaronj19772000@yahoo.com or acedaddie on this site from midland... thanx to any one who is willing to help with my questions.
