I have an apexi pen style timer in my turbo prelude..

I hooked the wires up the following way:

Car Turbo Timer
White/Black - Red
Yellow - Blue
Black/Yellow - Green
Ground it to a bolt on the fire wall - Black

WHen i take the key out the car shuts off..but if i turn the key one notch over (would usually shut the motor off) the car keeps running and times down, but like i said if i remove the key it shuts off.

Hopefully this is just a simple mistake on my end....

Also where do i tap the o2 sensor wire into.

Thanks
Steve

 

bumpppp

 

The white wire from the apexi auto timer goes to the oxygen sensor signal wire. Im guessing the oxygen sensor in your prelude is a 4 wire sensor. If this is the case, then it should have 2 black wires, 1 green and 1 white. The white wire from the auto timer goes to the white wire on the oxygen sensor.
