A bulkhead connector assembly for assembly within a downhole tool to isolate a dry side of the downhole tool from a fluid side of the downhole tool and to allow electrical communication therebetween. The bulkhead connector assembly comprises a bulkhead comprising holes extending therethrough, wherein the bulkhead is adapted to form a fluid seal against an inside surface of the downhole tool. Terminals extend through the bulkhead, wherein an end of each terminal is in electrical communication with one of a plurality of electrical wires. Boots each extend about the end of a corresponding one of the terminals. A retaining block has holes each receiving one of the boots. A housing positioned around the retaining block is coupled to the bulkhead, thus positionally fixing the retaining block relative to the bulkhead.
