Had a friend helping me put together a 1998 Merc 200 EFI.

We put in new rings and had injectors cleaned. Putting motor back together when friend left town with job assignment.

Trying to finish putting together and need help identifying where the 3 ground wires connected to front of injector plate need connecting.

There are three wires connected to the injector cover behind the ECU (1 appears to be 12 gauge and the other 2 are 16 gauge)

If someone could help me determine properly where those three ground wires are suppose to go I would appreciate the help.

I will post a picture later this weekend.

If you can send me some pics of where to connect them that would be great.

Thanks for your help.

Fyi... Once I get this together it will be for sale since I lost my job in June.
