MRX Posted November 20, 2004 Share Posted November 20, 2004 I have read various threads and checked out Peter Betts informative info on the conversion but I still have one problem... When I brought my 93 Jspec N/A Supra the Importer gave me a speedo converter and some instructions which I was happy to take away. Now, when it came to installing the widget I ran into a slight problem in that I dont think the widget quite matched the instructions... It has 4 wires +12 / Ground / Input / Output which I wired in with no problem. The problem came when the instructions mentioned the connection of a GREY wire... which my widget did not have . The unit is installed and converts the spreedo fine and will convert the Odo if I decide to wire it to it... This grey wire is supposed to to be connected to the Pink wire on the back of the Odomoter connecter and therefore remove the speed delimiter. Can I get round this with the wires that I have ? the normal input signal from the speed sensor and the output from the widget ? or is this some kind of completely different signal ?

SimonB Posted November 21, 2004 Share Posted November 21, 2004 Just buy a TRL one and do it properly. Otherwise you will end up with the steering too light, the air con fan blowing too hard and various other niggles. All these things rely on a speed signal and think you're going slower than you are if you just convert the KPH signal to MPH. The TRL one has a separate 1:1 output and 1:1 clamped (i.e. delimited) wire to make sure all this stuff still sees a KPH signal. Oh, and otherwise you probably won't be delimited, just limited to 180 rather than 112. It really ruins the steering if you do it wrong, makes it horribly light and uncommunicative.
