Place I picked up the motor from included the ECU, complete harness, underwood fuse box (that's going away) and the throttle body. Has the alternator and ps pump on it. Will be visiting a local shop that does tuning before I decide if I keep the factory stuff. Would like to keep the factory stuff. But if the $$ end of it is close to aftermarket stuff will have to think about. May look into Megasquirt...partially depends on what the tuner says...
