I have just put an engine back into a Defender 300TDi. Everything is back in place but I have lost the feed to the heater plugs and I have a single core red cable (Sheathed in the black corrugated plastic) left over which comes out of a loom by the fuel filter and is a bit on the long side to reach the back heater plug.
Is this loose cable for the heater plugs?
