Proportioning 2003 Toyota Solara SLE, Vin: 2T1CF28P03C602965.
The original brake proportioning valve on this car has 5 ports. I have checked a dozen OEM online parts stores. Nearly all of these sites state that the specified OEM Toyota replacement part is Part No. 47150-33020. However, that part has only 4 ports. What is the correct part number for a replacement proportioning valve for my car? Thank you for any assistance you can provide.
