Thread: VDO Tachometer

What Defender Tdi ?

I had one in a Tdi and it just ran off the alternator and worked well.

Can't remember he wiring though.

If you're going to bin it send it to me instead

Just google the VDO model and you should find the wiring diagram.

Edit - The colours for a VDO I have are as follows

Red - constant 12v
Black - ground -
Brown - 12v battery switched
Green - Sender signal + (ignition coil or Alternator W terminal
Blue/Red - Illumination +

Thanks for replies I have googled it but every thing but the wiring gets a mention it is a A2C53210902 I presume it fits a ECU type engine as it is adjusted by computor Will probably hook it up and frig around with it if it blows it blows
