Who knows what circuits some PO added, modified, or completely eliminated.. When a harness is hacked up as bad as yours, there is no cut and dried answers to your questions.. Scroll down through the forums and find the ELECTRICAL threads.. In the "Wiring Diagrams" threads, you will find files containing detailed in color wiring diagrams. Down load and print them. All of your questions will be answered by following and sorting the various circuits...

For starters, that brown /white tracer wire is part of the battery charging circuit.. It's a resistor wire that parallels the alternator charge light.. It runs from the ignition switch to the bulkhead connector and winds up at the external voltage regulator as a brown wire..
