I have thoroughly searched these forums over many hours for a source of the BECM Service Information Diagrams and there are several references to it at websites which no longer exist and by members of the forum who no longer exist. As others have suggested, it would be handy if functional links to all electrical documentation could be placed in the Sticky: Electrical Troubleshooting. If I ever get my hands on the whole lot I'll attempt to host it somewhere. Could anyone who has the BECM SID or knows of a functional link please respond? Thanks in anticipation.
