VDO gauges wiring

Sorry guys this seems to be a common question. I've done a search but haven't found the answers i need so here goes…

I've just bought 3 gauges.   oil pressure 0-5bar, Volts and a temp gauge.

I realise i need a sender and t-piece for the oil gauge.

Should the temp gauge be water temp or oil temp? Will i need a sender or can it be wired into existing sensors (and still be accurate)?

Would i be right in thinking i can just give the volts gauge an earth and wire it into any ignition live?

Just 1 more question, unrelated to the above.  Should the time clock in the main instrument cluster be back lit? once it goes dark i can hardly see it.

Hi Birty

Your guages are for oil pressure and oil temp .

You need a new seperate sender unit for the oil Temp and for the pressure guage try   
http://www.bigboystoys-uk.com they sell sender units.  

Volt meter is just ignition poz and neg , and yes the display should illuminate but MK1 clocks are renowed for being dim .

Cheers……….

Thanks chudd, I appreciate your comments. better see about getting some senders and getting them wired up!

i have hese gauges its been puzzeling me for ages trying toi wire them up,    so where does the pressure switch sit? why do you need a t piece? can some one post a pic up or something?

i have two senders that sit on the back of my head above my inlet manifold below my rocker cover. can i connect the oil temp up to one of these? of where can i connect it up to? help would be much appreciated

thanks and sorry if i sound dumb l:
