HOW-TO: Turbo Timer Install and How To
I have attached a PDF file to the end of this post; I will no longer worry about
re-hosting the pictures. I.e. if the pictures go down the PDF should still be
available.
Important Notes, Please Read:
*** Please do not PM/e-mail me with questions on this or other turbo timer
installations, I honestly can be of no assistance***
*** Please click me for my write-up on the blue HVAC and instrument cluster
lighting; again, please do not PM/e-mail me with questions regarding the

Okay, here goes...
*** UPDATED *** Jan. 6th, 2004 to include trim removal and speed signal
sensor wire!!
Well guys and girls, this past weekend I was able to install my turbo timer along with
my stereo. This made it easy to access everything because I had everything apart
basically. My friend won the GReddy Full Auto Timer unit from a car show and sold it to
me for cheap ($40) since he has a NA car. Here is a little how to with pictures for those
of you who are as unsure as I was whether or not you could or want to do the install
yourself. Enjoy but complete at your own risk!!!
Note-In order to use the auto feature on the turbo timer, it requires you to tap into the
speed signal wire on the ECU. This is somewhat difficult and requires going through the
firewall. Always be careful.
Tools needed:
Turbo Timer
Wire
Wire Tap-in Connectors
Butt Connectors
Phillips Screwdriver
Wire Crimping Tool
Knife (to cut tape)
Electrical Tape
1. Purchase your Turbo Timer - GReddy Full Auto Timer for me.

2. Decide where in your car you want to mound the turbo timer. For me it was under
the stereo in the perfectly sized storage bay.
3. Remove the negative battery terminal.
4. Remove the climate control knobs.
5. Roll the center vents forward and at the end of their range, keep twisting while
pulling the outside out towards you, thereby removing each vent.
6. Remove the two screws behind the vents.
7. Gently pull off the silver trim piece surrounding the stereo, climate control stuff,
storage bay, and vents.
8. Remove the storage bay by removing two screws.
9. Put a hole in the back of the bay big enough to push the turbo timer's wires through.
The unit is now ready to be connected.
10. Time to get to the Ignition Harness. This can be difficult as you are messing with
your precious interior. Use force tactfully.
First, loosen the dash. Pull the weather stripping away from the A-pillar and then
remove the A-pillar. Remove the screw holding the dash near the fuse cover. Loosen
the dash (it is held down by some clips).

11. Remove the screws at the underside of the steering column.
12. Now the gauge trim is able to come up. There are clips at each place where an
arrow points. Remove the section directly under the gauges and the steering column
cover.

13. Now remove the screws on the underside of the steering wheel.
14. The two plastic pieces surrounding the key receptacle should be loose from the
removal of the screws and removable by pushing one half in and pulling one half out
towards the back (held by a clip).
15. Locate the ignition wires which run from the key receptacle, under the steering
column, and then up and around the back left side.
16. Remove the piece of tape holding all wires together towards the top of their run.
17. Find the large red wire amongst the 8 or so wires and tap into it using the tap-in
connectors

connectors.
18. Feed the wire down to the turbo timer unit and connect it to the red wire(12v),
using a butt connector, off the back of the unit (you must first cut off the harness).
19. Find the thick sky blue wire amongst the 8 or so wires and tap into it using the
tap-in connectors.
20. Feed the wire down to the turbo timer unit and connect it to the green wire(ON),
using a butt connector, off the back of the unit.
21. Find the black and white wire amongst the 8 or so wires and tap into it using the
tap-in connectors. Sorry I didn't take a picture of this, but it is the only black and white
wire in the ignition wire group.

***ADDED 2008-04-17 - THERE IS SOME DISCUSSION IN THIS THREAD THAT
THE AIRBAG LIGHT WILL NOT COME ON IF YOU USE THE BLACK AND ORANGE
WIRE (INSTEAD OF BLACK AND WHITE ONE); I HAVE HAD ZERO PROBLEMS
WITH MY SETUP, DON’T MIND THE AIRBAG LIGHT AND THUS HAVE NOT
ADJUSTED MY SETUP; SO, READ THE THREAD (I RECOMMEND SEARCHING
THE THREAD FOR “ORANGE”) AND MAKE THE DECISION FOR YOURSELF ***
22. Feed the wire down to the turbo timer unit and connect it to the blue wire(ACC),
using a butt connector, off the back of the unit.
23. Now all of you ignition wires should be connected and look like this.
24. Now for the parking brake safety feature. In the passenger foot well, find the group
of wires near where the highest point of the meeting of the center console and carpet.
25. Remove the tape from that section and find the white wire with black stripe.
Tap into it using one of the tap-in connectors.

26. Feed the wire back to the turbo timer unit and connect it to the brown wire using
the butt connector.
27. Now time for the ever elusive speed signal wire. I found it easiest to remove the air
box and the battery.
28. Remove the harnesses entering the ECU near the driver's side headlight.
29. Take the lowest harness (black connector) and find a good place to remove some of
the black wire loom and electrical tape.
30. Find the white and orange wire amongst the 15 or so wires and tap into it using
the tap-in connectors.
31. Feed the wire along the engine bay to the firewall behind the battery. There is a
small hole that enters the driver's foot well there almost directly behind the battery,
possibly off to the right a little bit.
Here is a picture of the wire coming off the ECU in the engine bay (outlined by the
red).

Here is a picture of my amp wire going through the firewall, you can use the same
hole.
32. Feed the wire down to the turbo timer unit and connect it to the purple
wire(speed signal sensor), using a butt connector, off the back of the unit.

33. Find a good grounding point and ground the black wire off the back of the unit to
somewhere in the car.
34. Your turbo timer is now fully connected. Replace the negative battery terminal and
try out the timer. Once you know it is working correctly, carefully replace all trim using
the reverse steps of what you did to remove it!!!
Here are some pics of my completed installation (along with the new head unit). Love
how the blues go together!!

Also, I installed a switch in the speed signal wire today. With the speed signal wire
attached, the turbo timer will shut the car off before its done counting down if it gets
any speed signal. Often, just sitting there motionless you can get a surge in volts or
whatever it takes. If you watch the speed on the unit you will occasionally see it jump
as high as 4 km/h.
With the switch installed, I will be able to connect and disconnect the speed wire at will.
ie. use it for speed and attack modes, but for countdown only use the 3 minute preset.
To Install a Switch on the Speed Wire:
Go to RadioShack, or equivalent, and get an inline switch. I chose one that is a button
that pushes down and springs back up. It should have two leads on the bottom. Take
the speedo wire and cut it somewhere accessible in the cabin. I cut it right under the
steering wheel. Attach both cut ends to the new switch (one to each lead). Wrap each
with electrical tape. Zip tie it so that it does not hang down. You are good to go.
