Right worked out why my temp guage doesnt work
The fact that there is no wire going to the sensor under the bonnet, So does anybody have a picture of the wire which goes to it and pics of where it comes from as they doesnt seem to be a wire in the surrounding area

Well sorted the problem myself after finally getting alook around the engine I realised that the wiring harness had been put in wrong from when the engine had been previously pulled out at some point. So i re routed the wiring the correct way wround the engine and hey presto I now have a temp guage working yeay!
