As I'm breaking my written off Xsara VTS I've decided to use the engine, loom & ecu in one of my 205's for a while.
I think I've found a wiring diagram (I'll attach it later) that references the later three plug MM1AP ecu like I have fitted to mine and the wiring looks simple enough to sort into my car.
I still need to find the same wires as with any other conversion for the ignition switched feeds, rev counter, K light, battery positive and fuel pump feed to connect into the 205 loom.
Does anyone know if the method to keep the ecu in an unlocked state is the same as with the earlier single plug ecu's of disconnecting the battery asap (within 10 seconds) after switching the ignition off.
