This Aquatica Ikelite Bulkhead (Replacement) can be used on the D90 and other recent Aquatica housings. The bulkhead allows you to attach a flash to an Aquatica housing with a Nikonos 5-pin sync cord. It gets connected to the Switchboard Circuit (#18915). The Switchboard Circuit has four 2 position switches. When all the switches are in the upper position, all 5 contacts are active, allowing you to use a TTL converter, or housed TTL compatible strobe when this is used as the main bulkhead. When the switches are in the lower position (default), only 2 contacts are active. So it will work in manual flash mode only. When used as a secondary bulkhead it is wired with only 2 contacts for manual strobe operation in order to avoid possible conflict with the camera's electronic circuit.
