A few  months ago I purchased an mi16 engine together with a wiring loom and ecu that had supposedly run in a different 205 already. Recently after alot of headaches and trying to figure out the plugs on the loom I've found out that it's a loom from a dkz engine and an ecu from a bx 1.9. I've seen mentions on the forum that this was sometimes done back in the day, so I'm not too worried about using the loom and ecu to swap the engine into my car in two weeks. But what are some things to look out for? I can't imagine the idle will be too amazing without the idle control valve connected (or do I just plug the sad plug into it?). Any helpful knowledge is appreciated
