2005 uk legacy ecu wiring.
 

Hi guy

I'm doing an engine swap using the engine from my legacy 2.0 non turbo,
I've been whittling down the loom trying to get to the point where I have only what I need to run the engine,

I have the biu module and sigma alarm that I'd like to remove,

Is it possible to use just the ecu to run the engine or are the other systems integrated?

Thanks Martin.
