Ive heard that the ep3 cable is needed for the k20 swap into eg/dc?. Also if someone could send me a link or reply on here as to what exact fuel/s.s lines & fpr, i'd need that'd be cool. And last but not least i was browsing H-R's techarticles and saw on the parts list that a charging, engine, and conversion harness is needed. Im aware that some sort of wiring harness needs to be applied, but i didnt know there were a total of 3 diff. ones. Thanks in advance for all responses.
