Does anyone know which car this applies to: https://archive.org/download/anti-lock-brakes-1-of-2_pdf/anti-lock-brakes-1-of-2.pdf - it's a hard question, I know. OCR'd: https://archive.org/stream/anti-lock-brakes-1-of-2_pdf/anti-lock-brakes-1-of-2_djvu.txt. The "Creation Date" of the PDF is "3/15/2006" and the author is "(c)2006 SPX-VFTIS". I did find this: https://www.linkedin.com/in/david-miklosi-47b8b74 - "SPX/VFTIS Automotive Supplier Jan 1992 – Feb 2003" and this https://www.pdf-archive.com/2016/07/03/uuid-p5-wiring-diagram/.
It's probably for a Buick/Pontiac with Magna Steer. It would be on a top of the line full size model.
OK. I'm thinking it most likely applies to a 1997 Buick LeSabre & less likely, it applies to a Buick Regal. Did both or either of those have Magna Steer? Were they top of the line full size models? IDK, I'll have to look it up. Here is part 2 of that wiring diagram: https://archive.org/details/anti-lock-brakes-2-of-2_pdf.
