hklaine Posted September 26, 2004 Share Posted September 26, 2004 Does anyone know where I can tap into the vehicle speed signal? Thanks. -Heikki Link to comment Share on other sites More sharing options...
GLCraig Posted September 26, 2004 Share Posted September 26, 2004 Some kind of speed signal should be present at the cruse control brain. Link to comment Share on other sites More sharing options...
hklaine Posted September 27, 2004 Author Share Posted September 27, 2004 Where can the cruise control brain be found? I see that there is a cruise actuator on the firewall but it doesn't seem to have wires connected to it. Anyone have a pinout for the cruise brain or the ECM? I would prefer to find a source at the cruise as this seems to be safer than using the ABS system and cheaper in case of problems than using the ECM. Thanks. -Heikki Link to comment Share on other sites More sharing options...
99obw Posted September 27, 2004 Share Posted September 27, 2004 Depending on what you are trying to do, the OBDII system may be usefull. It's really hard to hold meter probes on the computer pins while driving. Of course you could attach some wires to the harness and run them to your meter. You could use a scan tool, custom electronics, or a device such as the car chip to get the speed data off of the car's network. Are you trying to diagnose a speed sensor or are you doing something else? Link to comment Share on other sites More sharing options...
hklaine Posted September 27, 2004 Author Share Posted September 27, 2004 I am looking for a source that I can attach a tap to permanently so as to run a speed signal to a naviagtion system (hopefully). -Heikki Link to comment Share on other sites More sharing options...
99obw Posted September 27, 2004 Share Posted September 27, 2004 What is the nature of the signal that the navigation system desires? Link to comment Share on other sites More sharing options...
hklaine Posted September 27, 2004 Author Share Posted September 27, 2004 Speed signal 0.5Hz - 4 kHz /square wave signal Low-level <1.5V high-level 5V-16V I may have just found something. A guide I came across online states that such a signal may be available from a green/black wire in a harness under the passenger kick panel. I'll have to take a look and see if I can't find it. -Heikki Link to comment Share on other sites More sharing options...

hklaine Posted October 25, 2005 Author Share Posted October 25, 2005 I ended up taking the speed signal off the back of the instrument cluster (the source for the speedometer). No complaints. Works great. -Heikki Link to comment Share on other sites More sharing options...
