i want to swap engine from honda civic ex 2001 vec d17a2 to the 2002 honda civic lx engine d17a1. because i want to know if the engine plug is the same or if its different. and i want to know if the computer is the same or different and how to swap

 

Engine, engine wiring harness, exhaust components, ECU, and some emissions components are different. Once the engine is swapped, you'll need a Honda technician to pair the immobilizer properly as well, since the engine won't start without it.

 

what is the ECU and immobilizer, i just want to know if the wire harness from my honda civic lx 2002, fit the honda civic ex vtec 2001 computer componets, if the control panel wire from the 2001 vtec fit the computer of the 2002 thank sincerly

 

You may want to do some more research on the swap, if the terms "ECU" and "immobilizer" are foreign to you. They're crucial components in the operation of the engine.
