hi there!
got same problems, but I have 1.8 lfz(xu7 8v) old engine
and I want to install rfv(2.0 16 v from 605 1995) Bosch 5.1
so I also looking for some wiring diagram
and I can't find any scheme of that connectors
and, theoretica, I can start the 2.0 engine, using a loops from 1.8?
they are the same, but I want use an ecu from 1.8 to launch 2.0
is that possible?
thanks in advance

Even if you did get the 2.0 16v to start using the 1.8 ECU I expect it would run pretty badly. I doubt you'd be able to remap the 1.8v ECU either. Get yourself a Bosch MP5.2 ECU designed for the 2.0 26v engine. There were different maps depending on the injectors fitted (see https://www.306oc.co.uk/forum/showthread.php?tid=36149). I can dig out the Bosch codes for the ECUs fitted to the 306's but don't know what the codes were for other models (406, 605 etc). You'd need an unlocked ECU (preferably hard unlocked).

Below are the Bosch MP5.2 ECU part numbers for the XU10j4R engine on the 306:

0 261 204 689 - for use with 186cc injectors
0 261 204 652 - for use with 200cc injectors
