hi i have a 2009 is250 rwd, i found a 06 is250 rwd engine and was gunna swap it, the engine comes with the wiring harness but not the ecu, would i be able to just plug and play or would i need the ecu from the 06 and have to put that in instead of running off the original 09 ecu ? thank you for any help

 

Same same, should be straightforward.
