Peugeot 206 KFW

Im after a better wiring diagram than the one i have from Autodata, and some pin identification if anyone can help.
This vehicle was parked up one night running fine, next morning would not start, it has no MIL illuminating with ign on, checked all earths, replaced transponder aeriel with a known good one, cant really go any further without knowing pin data for ecu, and both multi functions.
Any help would be much appreciated as i dont like sending them off to dealer.
Forgot to say, i cant get comms with dec or modis for any system apart from BSI and that has a permenant fault with comms at alarm control module.
