Hi again, Iam looking for the engine diagnostic lead (engine to laptop) for my 1995 LS400. What are they called and where do I get them from?

Thanks again all,
Brian

The 1st place to look is Ebay but they seem to do the scanner and leads but you may find something here

Or if you have a copy of Car Mechanics magazine there are various companies that supply the adaptors and necessary software.
If you cannot find anything let me know and I will find out some details for you.
