Scarface GTti Posted August 31, 2004 Share Posted August 31, 2004 Have the above turbo timer and have just purchased the correct harness to fit. I`ll be able to find where to plug it near the ignition but being an idiot with electrics does anyone know if the parking brake has to be wired into it? There is a brown and purple wire coming off the harness which appears to be optional? and as i read it, one goes to the handbrake and one goes to the back of the speedo? Do i need these two wires wiring in? on my 94 J-Spec TT6? Any help very gratefully received. Link to comment Share on other sites More sharing options...
SimonB Posted August 31, 2004 Share Posted August 31, 2004 The handbrake one is optional. It turns off the engine immediately if anyone releases the handbrake (i.e. to drive off in your car!). Dunno about the other one. Is is supposed to be for RPM so the timer can work out how long to let it run for or something? Link to comment Share on other sites More sharing options...
Supra ST Myster Posted August 31, 2004 Share Posted August 31, 2004 The Greddy Turbo timer has a function that shows your speed so thats what the purple wire is for,goes to the speedo... and i think thats how it works out how long to leave the car running when in the auto mode... brown wire is the handbrake which doesnt have to be connected but advised to do it as said above it cuts the engine straight away when its down, plus its not that hard to do, just lift up the gear surround section and you will see two wires from the handbrake, need the one that switches the 0V not the one with permanent 0V..

Scarface GTti Posted August 31, 2004 Author Share Posted August 31, 2004 Thanks guys. Don`t suppose you know which wire it would be for RPM or how i would find it as i don`t know how i would find that one. Link to comment Share on other sites More sharing options...
Supra ST Myster Posted August 31, 2004 Share Posted August 31, 2004 the wire is for the speedo not rpm, so when unscrew the Gauge cluster the far left connector from front view, there will be a blue/red wire in it, think its the 5th wire along again from the left, thats the speed wire so tap the purple wire onto this one!! hope that helps..
