Back Up Light Switch for all 1.9l manual transmission, early 2.1l and Syncro Vanagon after 88

Back Up Light Switch for Vanagons. 83-8/87 2wd Vanagon, 88-92 Syncro. Not sure why VW did this but they changed the back up light switch on their manual transmission vans several times. It wasn't to update to a superior design because they actually went back to it in the later syncros. They used 251941521 on 2wd Vans from 80-12/82, then this one up until 8/87 then 085941521 from 88-91. If you have an 86-87 Syncro the best thing to do would be to take a picture of what you have and I will match it up with what is available.
