I have a 1991 RR Vogue, 3.9 I am towing a caravan and need to know what I need to do to get the secondary electrical circuit operational.
I have set up the primary circuit via the connections behind the O/S rear light and I see two blanked off cables, I am presuming they have something to do with a split circuit system??????
Is the RR already set up with the spilt charging circuitry or do I need to fit the relays and diodes etc?????
many thanks
