May 11, 200520 yr Hi everyone, I have looked everywhere and had little luck finding the answer to my question.. I have a '90 legacy ls sedan auto, and I am trying to locate the VSS (Vehical Speed Sensor) output pin on the back of the instrument cluster. I have a gps unit that requires a vss input. I know that the car senses its speed from the head unit speedometer, but where does it output a signal to the ecu (or elsewhere)???? Any help would be appreciated, a schematic would be awesome. Thanks, Scott
May 11, 200520 yr I don't know how similar our cars are, but mine had this wire on the back of the Instrument Cluster. If I remember correctly the wire is on the left side, part of a connnector with 2 or 3 wires - ? I apologize for the lack of detail but it was some time ago that I installed mine. -Heikki

Thanks,Scott Since you have an auto tranny, why don't you just take it from the one in the tranny (VSS1)?

May 12, 200520 yr Author Just a very oldschool delco telepath unit ('96 i believe) i picked up for free.. direction, distance and time to destination, programmable.. not too bad for nothing
May 13, 200520 yr Cool. I am also running an old basic NAVI (Becker Traffic Pro), but may be upgrading to a newER old unit, a Chrysler CrossFire NAVI. It's similar but a bit faster with newer map information. -Heikki
