cheers didnt get any instructions with them so do i wire the red to the white wire aswell as the green

red to ignition power
black to earth
green to the signal.

If the sender has 2 wires then that requires earthing too.

nope, that should be it. Does it illuminate? if it does then you have a decent power/earth.

Whats the minimum on the gauge? Could take time to warm up to the minimum temperature

yes illuminates fine the minimum is 40 could just be it needs time to heat up as you say im using a adaptor in the hose and it has a small threaded bit in the adaptor should i earth that too

Yes, otherwise it won't read.

Also give it time to heat up.

As an example, my Defi w/t gauge starts to move after about a minute, the car's own doesn't register until the Defi reaches 60 degrees.

ok will earth the hose adaptor tomorrow thought as i had earthed the sendor i wouldnt need to earth the hose adaptor aswell cheers guys

Maybe you don't need to if you have earthed the sender properly. Give it a temporary earth to check.
