I used these from Paddocks:

Dieselglow heater plugs with wires.(set of 4)
   Dieselglow heater plugs with wires.(set of 4) - SERIES
GAM100
   Â£17.75 ex VAT    

Modern type wired in Parallel, so if 1 fails the other 3 still work as against the original type which were wired in series, if 1 failed they all stopped working, like a christmas tree.
Alsolute doddle to do.

i forgot to say that it has a 2.5 td engine in it im only getting 10.45 volts out of the feed from the ignition switch

Most plugs (including the dieselglow type) wired in parallel claim to be rated for 11v but won't use any balast resistors to drop that from the 13 odd volts from the battery (the dieselglow type say you should keep the series style balast resistor in their instructions but its wrong! If you leave it in they won't work very well!).  I guess they load the battery suficently to give a resionable voltage drop as the engine won't have started.  If your getting under 11v from the wire when its not fitted to the heaterplug then that doesn't seem right - check wireing/terminals/batt voltage.  If thats what it is when the plugs are actully working its probubly normal but you can always check the wireing anyway?  

Just use some very stocky wireing, I think my VW has a 50A fuse for the heaterplugs so using wire with a simular rating would seem about right.  If your starter switch is the type where you need to hold the key in the heat position it'll probubly be switching the full load without a relay so you'll need to replace the wires to and from that.  Another option would be to fit a relay - the load is more than many are rated to so a petrol type starter selonoid is probubly a good unternative.

the glow plugs are wired in parrelle, and draw a huge amount of current. 10.5 volts at the glow plug is normal, dont worry about it. you should worry if there is 12 volts at the glow plugs , that means some of them arnt working.
