I think the biggest problem with the LS engines is using the factory harness and ecm because of the anti theft yea got 3 choices I think do aftermarket like Always broke says which is nice but I think very costly, Get someone to do it for u or do the harness ur self but I think u still need to send the computer to someone that has the software to change it. Nice ride 4skin
