rupetorun Posted May 11, 2005 Share Posted May 11, 2005 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 Quote Link to comment Share on other sites More sharing options...
hklaine Posted May 11, 2005 Share Posted May 11, 2005 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 Quote Link to comment Share on other sites More sharing options...

Thanks,Scott Since you have an auto tranny, why don't you just take it from the one in the tranny (VSS1)? Quote Link to comment Share on other sites More sharing options...

hklaine Posted May 12, 2005 Share Posted May 12, 2005 What kind of NAVI did you install? -Heikki Quote Link to comment Share on other sites More sharing options...
rupetorun Posted May 12, 2005 Author Share Posted May 12, 2005 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 Quote Link to comment Share on other sites More sharing options...
hklaine Posted May 13, 2005 Share Posted May 13, 2005 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 Quote Link to comment Share on other sites More sharing options...
