I spent about 1 week, trying to find out where the VSS wire is on an 1999 Lexus sc300. I think this wire is same for 1998-2000.

I got my diagrams on ALLDATA.com

The last pic with the acutal wire tapped is from clublexus.com

You should move this to the Vehicle Specific Wiring section. I am sure it will help others in the future

if u send me the link i will.

i wanted to put it there, but could not find. I'm justing using the search function.
