Please note: From our experience and the experiences of dozens of our customers, we strongly recommend that the engine, harness and ECU all come from the same car!


If you don't choose to heed the above warning and buy a bargain engine without all the associated parts, put all the money you saved in an account. You will need it later for headache medications.
