Ok it's not working i don't know why....

i spliced the red (defi) to the radio 12v power (one in the top right three, in the middle (blue and red wire))

then...

i spliced the oragne and black to cigarette lighter. and white to cigarette bulb.

i'm getting the illumination when turning on the light but not getting any movement in the gauges nor gauges response when "warning set" and "peak" are pressed.

Can some one help me out?

Maybe this will help I assume it's the same type of unit.

TROUBLE SHOOTING

If you believe that the product is not working correctly, please check to see if it has been installed correctly before contacting us.
Is the fuse burned out?
Does the battery supply 12V to IGN when the ignition is on?
Are the engine revolution speed and vehicle speed displayed correctly?
Are the control unit and the display unit connected correctly?
Is there anything loose connections?
Has the unit been set correctly for the number of speed pulses for the vehicle's ECU and for the number of cylinders?
Does your engine have an aftermarket or non-OEM computer?
Does your vehicle have a speed governor release equipment?
Restart the vehicle and check the operation of the product.

PROBLEM CHECK THE FOLLOWING
There is no display. *Are all the wires connected properly?
*Are the connections tight?
*Is the GND wire properly connected?
Strange values are displayed. *Are all the wires connected properly?
*Is the tire size standard to the vehicle?
*Is your vehicle model compatible with the product?
Strange values are displayed and the instrument fails to function properly. *It is possible that the computer inside the product may be malfunctioning due to a radio frequency interference in your vehicle. Restart the vehicle and check its operation again.



FAQ
INSTALLATION
Do I need wiring for the product ?
Yes. You need wiring for IGN(power), GND(ground), SP(speedometer) signal and TA(tachometer) signal from the ECU(Engine Computer Unit) of your vehicle.


Can the product be installed on all models of vehicles ?
The product can be installed on certain models of 4 cycles 3, 4, 5 and 6 cylinder vehicles. However, the Tachometer display cannot be used on diesel engine vehicles.


Can the product be installed on vehicles without an ECU ?
The product cannot be installed on vehicles where a SP signal is not available at the ECU, unless the vehicle is equipped with an aftermarket SP sensor.


I have a diesel vehicle. Will SP work ?
Yes, if the SP signal is connected to the ECU.


Why doesn't the TA tachometer display function work on diesel vehicles ?
This is because diesel vehicles have no spark plugs, so there is no standard electrical signal output. (Some recent diesel vehicles have electronic controls.)


Is it possible to install the product on vehicles without a tachometer ?
If the tachometer signal can be obtained from the ECU, it is possible.



Can the product be used on cars if their computers have been replaced ?
It may be possible to obtain an SP signal from a replacement ECU. We are uncertain whether the TA signal cannot be interpreted on some replacement ECUs. ( From our tests, we have found that there is some malfunctioning. )


Can the product be used on cars with a modified ignition system ?
It depends on what parts have been changed. Generally, it can be used if the ignition system has not been altered. However, the company will not be held responsible for any problems arising from use of our products in a vehicle with modified ignition systems.


I obtain SP signal from my navigation system ; can I use the signal from there ?
We cannot guarantee proper functioning of the product by taking an SP signal from the navigation system.


Why has the Auto light(headlight controller) stopped functioning after installing V.S.D.II ?
Using both accessories places an increased load on the point of the vehicle electrical system where the product is attached which may result in failure of other devices. We recommend the use of either accessory separately.


When SP(TA) display is not needed, must the SP or TA wire be attached to the ECU leads?
No.



TECHNICAL
What if data displayed on the original vehicle instrumentation is different to that provided on the V.S.D.II display?
The equipment is not faulty. Please take the following steps.


If the difference is minor
Original Instrument calibration may vary by vehicle manufacturer. Our tests showed an average maximum variation of 4.35 MPH.
The VSD BASIS cannot be calibrated for individual vehicles. If you are concerned about the difference between the VSD BASIS display and that of the vehicle's original instrumentation, please drive according to the vehicle's original equipment.


If the difference is significant
The control unit may be broken. Contact your retailer.


What are IGN, GND, SP, TA, ILM and +B ?
IGN = 12V positive switched on when ignition is on.
GND = Ground
SP = Speed Signal.
TA = Engine Revolution Signal.
ILM = Light switch together with small lights.
+B = 12V positive.




OTHERS
Are there any plans to release a new version of V.S.D.II with an LED display color other than red or blue ?
No, there are no plans at the moment. If you have any suggestions for new products, please advise us by e-mail. Your feedback is important in our development of future products.

 

Need To Know Where And What Color The Speedo And Tach Wires Are. Trying To Hook Up A Defi Vsd Basis. Also Any Idea If I Set It Up As A 3 Or 4 Cylinder As It Doesn't Have An Option For 2(rotary)? Is Going In A 93 Fd.
Thanks

 

Red wire directly to Batt 12+
Orange connect to ignition switched 2 source(ie--not an accessory!)
White to an illumination source(search for my thread I created and I explain all)!
Black directly to Batt ground!

as for the switch position choose 4Cyl for 2 rotors!

Need more help just let me know and I can guide u through it...I just did mine not too long ago!

 

But What Color Is The Speedo Connection And The Tach Connection? And Where Do You Tap In At?
Thanks!

 

Tap in at the ECU...Check the FSM wiring diagram at the top of this section.

thanks for the help!!!

 

does anyone know what wire to tap on the ciggarrette lighter for the accessory? there is 4 wires going into and i dont have a volt meter
thanks

 

I tapped for accessory power at the key cylinder. Of course, I had a voltmeter and could pretty easily test the wires there. I don't remember which wire I tapped, but it was in the steering column... super easy to get to, which I like, given that it takes a minute to pop the column covers off instead of ten minutes of gentle prying and praying in removing the dash.

Not to be a dick, but you should have a voltmeter when you're working on any electrical system. You don't need anything fancy for basic work; a $25 rig should do. Not having it is like changing oil without a wrench. You can do it that way, but you'll probably eff something else up or wind up hurting yourself.

 

Also, to the OP and anyone else interested, I ran into some bizarre problems when installing my GReddy boost gauge. Everything was gravy when I didn't have the parking or driving lights going, but when I switched over, I got no reading on the gauge. I got power, I got illumination, but I didn't get a reading.

I'm sure everyone's aware, but the FD uses an alternating ground to control illumination... I didn't end up even using the illum wire in installing the gauge... power to ACC circuit, ign II from the turn signal tree, and ground from the ground side of the cluster illumination circuit. There wasn't a need for the separate illum wire.
