Replacement switchgear box and wiring harness for EQ Systems dual hydraulic jack leveling systems with a square, white 6-pin pump connector and 2-switch control. Direct replacement — no adapter harness required. Shipping weight 2 lbs, 10" × 10" × 2".
The EQ Systems 6704 is a replacement switchgear box and wiring harness for EQ Systems dual hydraulic jack leveling systems that use a square, white 6-pin connector where the switchgear plugs into the pump, and that operate with 2 individual switches — one per jack. Each switch independently controls extend and retract for its respective jack, allowing the two jacks to be operated separately or together.
Because the 6704 uses the same square white 6-pin connector as the pump, it is a direct replacement — no pump connector adapter harness is required. This sets it apart from the round white 4-pin switchgear options (#7815, #7816), which require an adapter harness included with those parts.
If you are unsure which switchgear part number your system requires, inspect the pump connector on your existing harness — confirm the shape (square), color (white), and pin count (6) — and refer to the EQ Systems Switchgear Replacement Chart for confirmation.
The pump connector is the plug on the wiring harness where the switchgear connects to the hydraulic pump. To confirm the 6704 is correct for your system, inspect this connector before ordering: Shape: Square Color: White Pin count: 6 pins If your connector is square and black with 4 pins, refer to part #6540 (dual switch) or #6526 (single switch). If your connector is round and white with 4 pins, refer to part #7815 (2 switches) or #7816 (1 switch).
The 6704 is designed for dual hydraulic jack systems that use 2 separate switches — one per jack. If your dual jack system operates from a single switch, this is the wrong part. There is no single-switch variant with a square white 6-pin connector; if you have a single-switch dual jack system, check your pump connector type and refer to the Switchgear Replacement Chart for the correct part number.
