Genuine KTI Hydraulics 74-03 Four-Wire Pigtail — the quick-disconnect pigtail that connects your KTI 2-button OR 3-button dump trailer remote to the pump wiring harness on double-acting (power up / power down) hydraulic pumps. Compatible with KTI Double-Acting pumps and 2-button (KTI 395-55) and 3-button (KTI 398-1 / 398-7) remote systems built from 2015 forward.

✅ Confirmed by KTI: This 74-03 pigtail works with BOTH the 2-button and 3-button KTI remotes — same 4-wire connection on the pump side, same round quick-disconnect coupler. Choose either remote based on whether you need basic Up/Down control (2-button) or Up/Down/Gravity control (3-button).
