you can run it of the computer i have heard if you have major problems but unsure how to hook it up. Maybe another option if you cann't get it going the old fashioned way :b:

ok it is ezy i did it. the white is dash lights, red gose to your ignition possetiv, green,coil, black is earth, but i have the white and red going to the ignition together so when the car is on the techo light is on. The coil is up the frunt left it says push take it off and connect the green one its the back one .and for the ignition i used the back of the sigeret lighter. that was the ezyest to get to in my vl i dont no if its the best way but it works i did it 2 years ago

no worries thanks buddy theres got to be another way

On the coil there is whats called a Low Tension Lead. It basically gives a 12V output thats pulsed. I can't remember which one it is. White to your park lights. Power from your ignition. Earth goes to the chassis.

Tip: The tacho wire can also be located behind the dash. I used to get lazy when installing these and do it from inside the cabin.

yeah buddy there is one white wire one red wire one green wire and one black wire do u hook it to a electronic coil

You need to find that pulse wire. Do you have a multimeter? Using a multimeter you will find it. Hook the green wire upto it.

Using a LED test light will find it as well. A standard test light wont.

Alright buddy it's simple. I've had two tacho's in my VL since i've had it. The first tacho was wired into the harness in the engine bay and in the cabin. I made the stupid move of wiring into the ignition coil's own wiring harness and eventually that led to blowing up the tacho and the car not working so don't do it that way.

The latest way ive done it is all done inside the cabin. When you take your upper instrument cover off and reveal the instrument cluster disconnect the upper connector, usually a white plug which power your warning lights. Then disconnect the black plug in the back of the instrument cluster itself. This is the wiring that controls 99% of what goes on inside the cluster. Then disconnect the speedo cable so you can remove the cluster. And obviously remove the mounting screws on either side so you dont break it. Once the cluster is out, go back to the plug that was connected to the back of the cluster itself. There somewhere should be a green wire, this should be your signal wire from the coil. If you cant find a green wire the go and look at the top or bottom of your instrument cluster. If your lucky it'll still have the factory sticker for the pin assignments for the main plug. Somwhere on there it'll tell you which pin is the signal wire.

Obviously you dont have a tacho in your dash otherwise you wouldnt need to put another one in like most noobs do. Don't quote me on this, and i could be wrong, but i dont think the dash needs this signal wire if there is no tacho in the cluster. So you can either cut it at the plug or just simply take the safer option like i did and just piggy back onto it to give you the coil wire for the tacho. Then like the other guys have said, white is your lights, either an accessory wire or parker lights, and then your black is negative, straight to battery post or to a damn good earth. Hope ya do it right! Good Luck!
