I recently had the opportunity to install a traction control memory module in a 2006 G35 coupe (thank you to LSHatch).

The install was a snap, still by far the easiest KPtech module to install.

There are only three wires, switched power, ground, and VDC switch signal.

On top of that, there is only one screw to remove to remove the lower dash. The screw is located in the bottom left corner of the panel.

Once the screw is removed gently pull on the lower dash and it will unsnap. There is a hose and a wire harness to disconnect on the right hand side, and three harnesses to unclip on the left hand side of the panel.

The hood release is connected to this panel also, but it is NOT necessary to remove/unhook it. With the other things disconnected you should be able to lay the panel on the floor board and continue with it there.

One of the harnesses that was disconnected from the left side of the panel was the VDC switch harness. In this harness you will find a black wire and a red/white wire.



The black wire connects to the black (ground) wire on the KPtech module. The red/white wire connects to the KPtech orange wire (Switch In/Out). I chose to solder and tape these connections, and that is still the preferred and recomended way of making the connections. The red/white wire will read 5vdc under normal circumstances and 0vdc when the VDC button is pushed.

To find the final wire you need to dig in the big harness that runs above the drivers kick panel. This harness is wrapped with a vinyl type material that can be 'unpeeled'. Inside the harness you will find a white/blue wire that only reads 12vdc when the ignition is turned on. Connect the yellow (IGN) wire of the KPtech module to this wire and you're done!



The module was tucked up inside the dash and the included wire ties were used to secure it.

 

I installed this module several weeks ago and had one question, do I need to add a fuse to the power line, maybe say a 2A inline fuse to protect the VDC module, or does it have it's own intenal fuse?

Thanks

It all depends on the application.

In the application above a 3A fuse was used. It comes down to where you are tapping power. If you are tapping power from a critical component in the vehicle (ie BCM, Ignition, ECU, etc) then a fuse should be used. If power is tapped in a none critical area, such as cigarette lighter, dome light circuit, etc (not that you would use the dome light for this module, it was just an example) then a fuse would not be required, as the OEM fuse will suffice.

The fuse is NOT to protect the module at all, it is intended to protect the wiring in the car. If the module is blowing fuses the module is defective. If the power supply in the module shorts out and no fuse is supplied then it will blow the OEM fuse that is on the power line (all power lines have OEM fuses). If you are hooked to an ignition source you'll blow a big fuse, and most likely the car won't start. So, to remedy this, you put a small fuse in line that will blow before the big fuse does.

Hope this clears it up a bit.

 

yup this helped alot

thanks

P.S I am plugged into a spot on the fuse panel behind the dead pedal
so I plan on placing a 2A fuse inline with this connection

 

Bump for a good DIY. Made it easier for me, thats for sure!

 

sorry but what exactly does the VDC memory module do? I looked on your website and don't quite understand

 

It stores the setting on the VDC so it doesn't reset every time you shut the car off. So you only have to turn it off once, not every time you start the car.

 

I find with mine if I leave the vdc off for more than 15 mins it tosses on a buncha lights. I think it's the slip and one other I can't remember right now.

 

...That is not normal. I've had mine off pretty much since I bought the car and there aren't any wierd lights on.

 

i always keep mine on.... since my throttle body sensor went out and it went into limp mode i havent wanted to turn it off. i have a feeling something will **** up and lights will come on :[
