Purple wire

[Davidle]

I have a greddy turbo timer and was wondering where the purple wire goes to. i checked out the greddy website and it says to the ecu speed signal. which wire or color is that on the ecu?? thanks for all the help. i have a 95 GSX.

Im not sure why you posted this in fuel tuning but Ill move it to 2.0 turbo discussion..

BTW, did you buy the harness? Im trying to remember what other wires there were, Im thinking one is brown and one is purple. if thats the case one goes to the clutch pedal and the other to the ebrake.

I wanna say it's the ebrake myself, but don't wanna give out bogus info.

i am going to get the harness. the brown one goes to the ebrake, the purple is the one i dont know. it goes to the clutch pedal? wheres that? is there a wire for it? thanks for helping me out.

not sure, i didnt hook that one up.. the brown and purple wires are both safety wires, they make sure no one can steal the car.. It will shut off the turbo timer and the car if you put down the ebrake or step on the clutch, they work independently of each other so no need to really hook up both.

The purple is supposed to goto your tach lead to measure your count down based on RPM. You don't have to hook it up in a DSM as it will grab your RPM signal through your positive feed, just leave that and tape the end up.

Your timer will still work in the mode where it watches RPM and does the count down. If it doesn't work that way then you have an older version of the greddy TT and it needes to be hooked up.
