They published a book that was roughly the size of a small phone book every year of production for these vehicles that covered just the electrical diagrams and schematics. And it’s a copyright violation to post them online. Maybe if you described the problem or what it is your trying to do, and you’ll find someone who has already found a solution will be able to offer some help. But if your just wanting electrical diagrams for an ‘02 GS430, you’ll find plenty of copies of the electrical diagram manual that I referenced above for sale on eBay.
something like this? Or there are also online versions available also, you can get a trial membership with full access for a few days for a very reasonable price.
