Best way is to use a schematic diagram of the wiring, and where you have suspect wires, work out where each wire connects to something, or joins into a connector, and do continuity checks, etc. That's how I worked out the wiring issue with the 85 900i. It can be very tedious if you're tracing a lot of wires, but in general, all the wiring in the engine bay is going to degrade much faster than elsewhere, but if your car doesn't have an exhaust shield under the floor the wiring running down the centre can also cook (and in one recent case I saw on a forum site, short and start a fire!). Also keep an eye on the rear light cluster wiring as that's a common place for water to get into the electrics.
