Richard,
What exactly do you want? I have the E82/E90 135i/335i wiring diagrams and service/shop manuals. A company that sponsors me manufactures a piggy-back computer, the CP-E Standback II DIEMS (Direct Injection Engine Management System). When installing it, the instructions require you to pop the pins out of the harnesses and plug in the Standback wires. These wires obviously tie into the Fuel, Igntion, boost, etc, or the important areas, to control the engine. Let me know what you need, i'd be glad to help. The shop / service manual and wiring diagrams are on CDs, so i can make you a copy and mail them across the pond
