Not sure which harness you need?

DBC vs DBW: DBC uses a throttle cable; DBW uses an electronic throttle body and pedal.
Gen III vs Gen IV: Confirm your PCM/ECM type and the year range of your engine package.
Auto vs Manual: Transmission choice changes wiring and control strategy requirements.
E40 note: 2005–2006 LS2 applications commonly use the E40 ECM; confirm ECM type before ordering.
