What is it you want to trace? If you have a problem with one particular function, check the fuses first

It is probably easier to describe what is NOT in the under-dash wiring. Your best bet is to get a multimeter and systematically probe for "hot" wires between the item you want to check and ground.

For example, the main beam lights and the side lights go to different poles on the switches. so place the probe onto the switch, then trace the wires from there and see if the meter shows 12+ volts.

Hi Phillip:
May I suggest that you google or try this link
There's a ton of pictures that are easier than me trying to describe it.

Start filling it with water. Watch for the leak.

If you provide us with Year Make & Model and short description of type of HTR/AC system (manual or auto) it would be easier to know where to look for a manual/schematic.
Also if you describe the problem you are trying to solve - chances are one of our experts here at "fixya" may be able to point you in the right direction to resolve your issue.

No fuel pressure, no spark, ignition switch, crank sensor, no injector pulse, blown fuses, starter, battery, neutral safety switch, bad connections, PCM, etc. The better you describe your symptom along with what you have checked the easier it is to get you pointed in the right direction.

your choice is to call a locksmith or a dealer. describe your problem and get a price. generally it is easier to take proof of ownership to a dealer and have them make you a new key.

Have an OBII scan done. (fault scan) Your description can describe many things and a scan will narrow it down to the exact faults. It's easier & cheaper than throwing parts at it. Trust me, I used to work for BMW NA

Where is it leaking from? Possible causes - hose, waterpump, heater core... If you can describe location of leak (area of engine) would make diagnosis easier,

Well, get the car up, take the tire off, Take a C clamp the bigger the better since it has ABS. Lock the C clamp on the hammers and tighten. Actually here is my email for diagram it would be easier to describe. onetigerone at hotmail dot com.
