Where is it?

I just installed a Greddy Turbo Timer, and I hooked everything up and it works great - except I do not know which wire I tap into for the speedometer function. The turbo timer comes with a purple wire that you need to tap into the speed sending wire, but I am not sure wich one. Could anyone help me find it?

Thanks guys!

Oh yah, anyone else have this timer: how to I set the screen color to be red instead of the normal blue?

 

There are 2 wires coming off the speedo to the speedo sensor. One is yellow/red, the other is yellow/white. I don't know which one you need. Use an in line splice. Don't cut the wires.

Oh yah, a turbo timer is a waste of money. Just drive the car easy before you shut it off.

yah but thats not always possible....

 

Needs to be tapped into the green wire at the emmissions harness by the ECU. Tapping it in here is easier than behind the dash.

 

this is a pic of the ecu wiring. I forget if this is a pic from behind the plug or in front of it, but it's easy to figure out if you compare the plug size to your wiring harness.
