    You can order an Allison Troubleshooting manual from www.allisontransmission.com, or use the service finder on their website to find a local dealer that can order one for you. That will get you the basic Allison wiring information and schematics which might be a big help, but it won't tell you the specific wiring schematic for your vehicle. The vehicle specific wiring information needs to come from the OEM. The Vectra is a Winnebago, isn't it?

    I am to assume this is WTECII which means your shift pad has a two digit display. When you get a schematic, you will want to check wires 136A, 136C, and 143A, 143C. These are your power and ground wires to the shift pad. If those both check out ok, than I would double check all connections at the ECU and at the shift pad. As db said, you will also need to get the wiring schematic from Winnebago to find out where the VIM (vehicle interface module) is located. Those usually have a fuse inside, that could have blown. I would start with those things, and see what you come up with, if you already havn't gotten it fixed..... :)
