you can use your dx harness just add a couple wires....then I had to buy a dizzy and swap my injectors over from my old motor....that plus mounts....grand total.......way less then the gen2....I mean if you can afford it go with the gen2 or a gsr..I would have if I could have...but I didnt have the loot at the time so I made due. I couldnt really wait cause I blew up the old one...I love my lil b16a even though everybody on HAN is a b16a hater:fawk:
