I saw a post on here a while back that showed someone fitting a coolant alarm using a coolant tank with the switch already fitted, wired thought the ECU and using a lamp on the dashboard that might only be in use in Japanese versions (if that makes sense). Unfortunately, I have lost the link that I had to that and my searches so far have been unfruitful. Can anyone help me find the said post? I'm keen to fit an alarm to my 04 TF. I have the tank but need the guidance of someone that managed it before. Thanks
