Too late, they're gone. Once removed, the only wires external to the relays and batteries were the alternator trigger wire (no longer needed) and the output which runs up to the control unit on the wardrobe. This latter wire I traced with my meter and replaced it with the positive from new leisure battery. It could just be a bad output connection in the control unit as the lights work fine as does the battery indicator and water level meter. At least next week I've only got the heater and water pump to solve.
Very difficult with everything screwed down, to determine where either are connected.
Will work using this diagram I think as control unit (DS220D) is identical and its an autosleeper diagram.
