While I was fitting in my Road Angel yesterday I took the top dash off my car (Mk1 Ph3 1.2 Oasis) and spotted a blue plug thing tied in with all the wires but not connected to anything. It was resting near the top left side of the speedometer unit. Could this plug be the one that goes into the oil cradle with the guages, like on on Rsi's/Valvers,Williams??
