There are 2 possible problems

1. You have a faulty or incorrect sender/sensor

2. The thread of the sender/sensor is not making an electrical contact with the thread in the thermostat housing. ( this happens if you use thread tape or a thread sealant )

You have already proved that the wirring is good.

Got nothing to do with thermostat or coolant. Even if the the thermostat was stuffed the engine would heat up.

Dont confuse the thermostat with the temprature sender/sensor.

Funny you should say about the thread as I've used ptfe on the threads to seal it, should you use nothing on the threads then?
Thank you mate appreciate the help.

Thread tape ( especially ptfe/teflon ) are very good insulators. Actually they are the best in terms of electrical insulation.

Aviation gasket goo can be used instead.

Try it without any tape/sealer. If it leaks put tape or sealer on the final section of the thread so that the first section can make metal-metal contact.

Was it a sealer or similar stopping the connection?

Yes... inquiring minds want to know what you did to fix the problem.

 

For what it is worth, the sending units (mechanical and electric) are supposed to seal on that conical surface machined into the head and on the sender.  Thread tape or sealer is really secondary to that surface.  Therefore, I suppose it would be prudent in any electrical sending unit replacement to make sure the conical surfaces on the head and sender are both clean and free of corrosion to insure both electrical contact and mechanical sealing.

Well I replaced the sensor for new and did away with the tape on the threads and it works fine could have been a faulty sensor thow
