I need to know where the wiring harness comes from for the front radar on a BMW E90 (3-series) vehicle equipped with the 'Active Cruise Control' (ie. ACC) option. Please link to pics of where the harness connects to the radar and where the harness joins the main wiring harness for the vehicle. Thanks.
What you need is ALLDATA(online service manual). This will have the wiring harness diagram that you need. There is even a cannon plug connector diagram that can tell you which wires go where. It's about thirty bucks a year per car, but is worth it for all the information that it contains.
