First, you'll more than likely want the
whole brake master, which is 47050-60041
BRAKE BOOSTER ASSY, W/MASTER CYLINDER 07.1999-08.2000, not just Master.
Your VIN should tell you. If you use it, when ordering, you're covered for replacement if they say it's correct.
The difference in 2000, is wire housing block for pressure sensor. Build date July 1999 thru Aug 2000 Type A (89637-30030 SENSOR, OIL PRESSURE July 99 08.2000, pressure SW inline wire) Master w/booster P/N ending in 41.
All, after that date, have type B oil pressure sensor. Which is triangular shape wire housing block to sensor.
So look at your Brake booster assy w/Master cylinder. See which sensor. Then punch VIN # in at
www.partsouq.com. Check it's parts diagram for pressure sensor in the master.
My notes say build date thru to Aug 2000. My recollection is up to January 2000 is type B. Sensor is the key to getting correct master.
