I put in a 38 and had to use the ABVW panel but I still want a water temp gage. I'm looking for a second port to mount the temp sensor since I still want to keep the alarm on the ABVW panel active but can't find a second port. I'm thinking of putting a "T" at the calorifier output port and adding the new sensor there. Any other suggestions or is there a port I've missed? Thanks!
