I was quite worried about that plug so was very careful not to damage any part of the original fitting so it could go right back in if there were any complaints. But there were no complaints, errors, etc.Very smart are you going to do the other one an did having the heating plug disconnected put up any lights .
Been too busy to research where that other hose goes. I’ll fit it if I’m capable but, as I said above, I have grave doubts
