    Hello,

    I'm investigating an ignition problem on bank 5-8 and after looking to the wiring diagram, I'm looking for "Connection for cable multiplication item" also referenced as "40158" in mondial T workshop manuel. I can not find where this item is ? Does anyone know this ?
    Thanks.

    Cable multiplication item normally refers to a place where one wire branches off into multiple wires going to multiple locations. It's a fan-out connection. It could be a crimp with multiple wires, or a stud where many wires are attached.

    Perhaps you can describe what your ignition problem is and ask for help that way.

    Here's a wiring diagram:

    The 02406 and 02494 on the top right are respectively the coil for spark, and his associated power module for coil and 10514 at the bottom is the T55 connector for the motronic. All coming from "Workshop Manual for Mondial T".
    I'm missing power supply on my power module near to the coil on one side (bank 5-8) thus I would like to check the 40158 and 40165 mutliplication in order to see if there's no bad contact or bad ground.

    Find connector 41037, find the pin 2 (cannot see the number very well), follow that wire inside its harness and you will find a splice where one wire becomes 2 wires, one going to 10514 and the other going to 02406.

    Unfortunately, engine harness "cable multiplications" are often found under the black plastic sheaths and impossible to find.

    I've seen a similar ignition problems on 355's and it was found to be in a section of harness in the engine bay which may have been damaged during an engine out not far from the ECU.

    Sorry, I can't help with 41037. If you can find a photo of the harness for sale, sometimes you an get an idea of where the plug is in relation to the ECU. The parts manuals also give you some idea.

    That smaller plug in the diagram above appears in this picture.

    Unfortunately, I can't make out the wire colours. Some of them look rather thin, so may not be suitable for ignition wires.

    It looks like that is located in the rear luggage compartment sidewall behind (or next to) the wheel arch.
