Easy fix last night for this, the connector in the door for the warning display wasn't plugged in
It was tucked down inside each rear door so once i found the plug i connected it and it works as it should. I haven't looked at the red temp sensor yet but i suspect that it's basically the same issue.
****NOTE***** Ont the 2wd there are 2 wires for the warning display sensor in the loom going to the door, but on the 4x4 doors there are 3 wires that the other end of the plug connects to. The connector just plugs straight in and it works so I don't know what the 3rd wire is for, but it works without it being connected.
