Guest dmk2123 Posted November 15, 2003 Share Posted November 15, 2003 Does anyone know what wire carries the speed signal from the ECU. I need this so I can hook up my turbo timer so I can make use of the Speedometer feature Quote Link to comment Share on other sites More sharing options...

fl327 Posted November 17, 2003 Share Posted November 17, 2003 /speed signal for what? do you mean speedometer cable Quote Link to comment Share on other sites More sharing options...
datsunan Posted April 5, 2004 Share Posted April 5, 2004 It is generated by a magnet and pick-up in the speedo, 240,260s did not have the pick-ups, I had to install my own. It is a 2p pulse, two pulses per rotation. The magnet is located in the speedo case and is what causes your speedo needle to move. Rip out the the pick-up from a 280 and find a spot to put it near the magnet, hook up a meter on continueity and spin the speedo cable. You should get 2 beeps per rotation. Hook 12 volts to one wire and run the other to your sorce,ie timer boost controler. Quote Link to comment Share on other sites More sharing options...
Guest De Schmaydee Posted April 9, 2004 Share Posted April 9, 2004 on an "82"ZXT....the speed sensor (its just a switch) is connected to the yellow/white and yellow/blue wires located on the "white" (10 conductor) plug of the dash wiring harness. you'll prbly need to take off the passenger's threater lamp panel (and maybe the panel around the fusebox) to see the plugs....there are: blue,white,brown,green plugs all the same size (10c)....you'll be dealing w/the white one.....hope that makes sense... dont know if the 83 is the same...you can unplug the white plug and hook a test lamp (w/a battery) in series w/these wires and the lamp should flicker as you move the car slowly... ....s Quote Link to comment Share on other sites More sharing options...
