As you probably know "brown" wires are usually ground wires. I can't help you beyond that, sorry. What I tell you is go on line with our host and buy a Bentley's manual. You'll want it for a lot of reasons, one being that it has the wiring diagram for your car in the back of the manual. With a little time it's understandable to a lay person like myself. Anyway it's a good start to solving your problem.
