   Hi, Im a new member to Saxperience.Busy helping a mate with a 16V conversion from an 8V.
   
   We are having issues as the engine is a 106GTI we have a loom supposedly from a 2002 Saxo which runs Magnetti Marelli 48P management (3 Plug ECU) which we are using and is unlocked . The issue we are having is we are struggling to find either the pin out from the ECU relevant to the injectors or the wire colour codes for the relevant injector cylinder numbers as the plug is missing from the loom he got.
   
   We have isolated the wires to a GREY , LILAC, GREY, BROWN and ORANGE. I have autodata but it shows a common connection to each injector then injectors 1 and 4 then 2 and 3 connected in pairs back to the ECU but I think this is the single large connector type ECU wiring diagram im looking at, in other words not the 3 plug ECU by MM . Also given I have 5 wires I think each injector is fired seperately on the MM ECU with a common being the fifth connection.
   
   If anyone out their knows the colour codes for these wires or the relevant pin out for the 3 plug ECU I would be very grateful...
   
   Cheers

   Would it not just be easier to find the correct loom and just plug and play? Parts on these cars are pretty easy to find.
