!!!Caution/Achtung/Attenzione!!!

Follow this guide at your own risk. You have been warned. We are not responsible for any actions you take. The information contained herein is a guide and should *not* be acted upon with consultation from your local tuner (he/she may not agree with my comments / suggestions). If you are unsure or are not confident don't do it.

This guide shows you how to disable the door unlock button on the R33 Skyline. It is a common known security flaw that this button works when the car is locked/alarm is on. Thieves can bend back your window and then press this button to unlock the passenger door. Once this has been done they are free to enter your car and do as they please. The factory alarm doesn't seem to be triggered by this break in method.

Tools you will need;

Phillipshead Screwdriver

Electrical Tape

Scissors or Pliers

1. Open driver side door. Remove the screw cover inside the door handle area and undo the phillips head screw. Carefully lift up the Power Window / Door Button harness cradle from the door.

2. Locate the wiring loom attached to the end of the controller unit and cut the Brown wire. Once this wire has been cut tape up both ends with Electrical tape.

3. Put keys into your ignition and turn to ACC. Test to see if the door unlock button works. It shouldn't

4. Tape up the remaining part of the loom and place the cradle back into the door. Screw it back into place and place the screw cover back on.

I have confirmation from one member that this wire is the same on the GTR33 and GTR34. The same brown wire disables the circuit on these cars

Sounds like a good idea, but you loose the door unlock function to go with it I take it? I do actually find this very handy as my alarm auto locks the doors when driving & I let passengers in & out with it a lot.

If you had a relay linked to the ignition power it would still allow this function to be used while securing your car when it is locked/alarmed too.

R34 GTT??

[paulr33]

youll have to pull out your door lock button and have a look.

i dont see why they would have changed it for the gtt.

the wiring should be common on all the skylines, at least you would expect

best idea. there is an IGN feed already there to do it.

just finished doin this on my dad's ceffy (which also has the same button in a similar position). Made sure the switch only worked when the alarm was disabled by using an alternate earth signal (which I got from the ignition switch).

I found that if you set the plastic switches on top of the control box incorrectly the passenger unlock button cant move ...

just another way to do this without cutting the wires i guess..

I have a '97 skyline r33 Series II. I tried pressing the passenger window button when i locked the car with the alarm on and the window didnt come down. I also tried it on the drivers side button while doors were closed and the window didnt come down. This exploit must of been fixed in the '97 skylines?

nope your talking about a completely different button... its not the power window switches..

its the passenger door unlock button.. Just below the passenger window button

[nuffsaid]

My brown wire has a red stripe going all the way down the middle of it

R34 GTT, is this the wire? haha dont want to cut it willy nilly =P

[justin911]

You need to buy a relay and switch it via the IGN wire on the connector.

If you need help i could do it for you, you just need to go to Jaycar, or wherever, and buy the relay.

oh ya i found the ign wire just now with the multimeter. think its the big yellow one.

couldnt i just chop the brown wire and connect it the yellow/ign ??

with the relay there will be 3 points ya ?? what would i connect them upto

thanks

[justin911]

oh ya also how many amps or woteva do i need? they got lots of relays

[justin911]

i got all the relays from the boot/bonnet from my gtst.. could i use any of them ? like the fuel one ??

[Al]

Have looked for the last 1/2hr for the farken life of me i can't find a simple farken wiring diagram for a common farken relay. Therefore i can't tell ya what to hook up to where.

THE WEB IS FULL OF USELESS SHIT!!!

You need one pin to hook to ACC

the 2nd to hook to GND

The 3rd to one half of the brown wire

The 4th to the other half of the brown wire.

I think it's:

Pin 86 => Acc

Pin 85 => GND

Pin 87 => 1st half of Brown wire

Pin 30 => 2nd half of Brown wire

Your common 10amp relay is more than enough.

[justin911]

ya i was looking on google 2.. 'howto use a relay' etc etc. then i got tired of looking and pm'd you

3 --/ -- 5

1 --88-- 2

is on the relay i got

That should be it!

Pin 1 = ACC

Pin 2 = GND

Pin 3 = 1st half of Brown wire

Pin 5 = 2nd half of Brown wire

thanks heaps again Al
