Is anybody in northern California doing or has done a LS swap in their third gen. The motor and tranny are easy but the wiring, fuel system, and EVAP are going to be a real pain in the ***. I think i might be needed some help on this one. Although some of you are giving some good detailed information i'm just scared of wiring. I hate it! I know you can send your OEM harness and the new LS2 ECM and harness to a shop and they'll make it work, "plug and play." Anybody ever use these? Are they easy to install? Thanks for any help guys.
