Quoting Pierson: The conditioner attaches to the battery via a two-prong (+ve and -ve) plug and matching socket, which when 'broken', enables the cable to be left permanently attached to the battery but the conditioner to be disconnected. The conditioner is a Halfords own unit and came with two sets of cables, one to connect and leave (as I have done) and the other with sprung terminal clips which can be attached as required.
As I don't need the second cable I cut off the plug and wired this as the fly-lead attached to the poles on the back of the accessory socket. I can hence disconnect this when I need to leave the car on the conditioner but re-connect the plugs when on the move to power the socket. Thanks. I wired my socket to the battery and put a cigar lighter plug on the lead from the charger...
