+1. Done this conversion a couple of times. The ring isn't coded, that's just the sensor for the transponder. All you will need is the key chip to match the ecu.
As for the mix/match loom it really is more hassle than it's worth. You could buy the correct ecu and engine loom for your vehicle for about £100.
I've heard if someone getting a conversion running in the same position as u, but the digi dash never worked as the ecu couldn't control it.
Think....buy the right bit and it's plug and play
