aww, your lucky then, first of all b/c you've got an s13 which i believe is easier and the write-up is better... second, you've got the entire harness, you may just have to re-pin a couple wires not sure on the s13.

i had mine hooked up about 4-5 different times, screwing with the damn thing and i know it wasn't the unit itself b/c we tested it on my buddies car. it looks so simple, but for me some reason it didn't end up that way. i'm just glad its over.
