abraham808 Posted November 20, 2007 Report Share Posted November 20, 2007 I posted this before. Now trying to post in the right place. This is how I found the VSS wire on a 1999 Lexus Sc300. You have to find the ECM. It's located under the passenger side dash. You have to peel the floor carpet back. You will see 2 screws that you can loosen. Quote Link to post Share on other sites
abraham808 Posted November 20, 2007 Author Report Share Posted November 20, 2007 Here is the wiring diagram that I used to find the VSS wire. It's the one near the top left. Light Blue with Yellow Stripe. Quote Link to post Share on other sites
abraham808 Posted November 20, 2007 Author Report Share Posted November 20, 2007 So if you look above you will see a "C". The "C" references "E17". The 5 means the position it is in the harness. This is the wire to tap into. Quote Link to post Share on other sites
abraham808 Posted November 20, 2007 Author Report Share Posted November 20, 2007 Finally this is a picture of the acutal wire you need to tap into for the VSS. I got this from ClubLexus.com. Good Luck and I hope this helps. Quote Link to post Share on other sites
