Planning a replacement or upgrade?
Use the replacement link and the applicable manuals to compare the current system with the installed equipment. Matching engine count alone does not establish that control heads, control units or harnesses interchange between generations.

Required separately and installation planning
- NM0649 bus harness — select one section for the single-engine, single-station layout. Confirm each route length against the applicable wiring diagram. Bus, power and engine-interface harnesses have different roles.
- 2 × CCX633 mechanical engine-control cables — one shift and one throttle cable per engine, selected for the actuator-to-engine or gearbox route.
- Configure the system using the control-unit settings described in the applicable legacy manual. Do not apply KE-XG programming instructions to a different generation.
- The listed power harnesses are 5m. Optional 10m power harnesses can be discussed when requesting the complete system quote.
- The applicable manual limits the total CANbus-harness run to 80m. Plan the complete layout rather than treating this as the allowance for each section.
Request complete system pricing to include the required harnesses, cables and other installation parts.
Station expansion and setup options
KE4+ supports up to four helm control heads plus one optional wired handheld station with the appropriate components.
- KE403A — matching additional-station kit
- NM0907-00 — optional wired single-engine handheld remote; match the socket harness and system generation.
Optional emergency mechanical backup: the actuator’s manual-operation arrangement requires the separate mechanical control head and cable components described in the applicable manual. These optional components are not included in the kit.
Planning a wireless docking remote? Ask Seatech to confirm the remote model, compatible control-system interface and additional hardware before ordering.

Which engine connections does KE403 use?
KE403 is the single-engine KE4+ configuration for mechanical shift and mechanical throttle. Confirm the engine and gearbox interfaces against the manual before installation.
Is the bus harness included in KE403?
No. The CANbus harness is ordered separately for the planned route. The included power harnesses do not replace the CANbus harness.
What is different about KE403 and KE403A?
KE403 is the base kit. The matching additional-station kit adds another helm to a compatible base installation and does not duplicate the base control unit or actuator hardware.
