This weekend I replaced my engine in my 2008 Jeep Wrangler with a engine from a 2010 Jeep Wrangler, the dealer is telling me the TIPM, the starter, and the wiring harness are different for those years. Can anybody tell me if this is correct and if I will have any issues. When I did the swap I used the starter, TIPM, and wiring harness for my 2008 motor.

After we had the engine all installed, when I hooked up the battery terminals without the key in the ignition the engine continued to turn over.... what am I missing here? Can anybody help me with my issues?
