395-CK001 Pendant Quick-Connect Service
- Identify the pendant pin connector and power-unit receptacle.
- Prepare and assemble the connector without twisting conductors.
- Verify wiring against the kit diagram before a controlled function check.
- 1/8-inch precision flat screwdriver — Secure conductors at their assigned wire screws; the instruction sheet provides no numerical screw torque.
- Cable jacket stripper — Remove the specified jacket length without cutting the insulation beneath it.
- Wire stripper — Strip conductor insulation without nicking or removing conductor strands.
- Ruler — Measure jacket removal and individual conductor strip lengths before termination.
- Multimeter — Check for electrical power at the work area after disconnecting all electrical sources.
The 395-CK001 Quick Connect Kit instructions in How-to-disassemble-Quick-Disconnect.pdf, page 1, identify the pin connector as the pendant-cable side and the receptacle as the power-unit side. These are electrical connectors, not hydraulic hose couplers.
Lower the trailer fully and disconnect all electrical power before starting. Mate the pin and receptacle connectors to keep the connector bodies from rotating while loosening or tightening their backshells. Use the locating key to prevent rotation rather than twisting the wires.
For the documented kit, remove 1-1/2 inches of cable jacket and strip 3/8 inch of insulation from each red, green, black and white wire. Slide the cable nut, clamping ring and backshell onto the cable before assembling conductors.
Connect each wire to its proper screw using the manual’s Figure 2 for the actual pin mapping; do not assume another KTI receiver’s colors or terminal numbers are equivalent. The sheet identifies a 1/8-inch precision flat screwdriver for wire screws but gives no numerical screw torque.
Reassemble and tighten the backshells while controlling connector rotation. Restore power only after assembly is complete and the trailer is safe for a controlled function check. If the diagram or connector identity is unavailable, stop rather than guessing the wiring.
How It Works
Connector identity and safe isolation
The 395-CK001 pin connector belongs on the pendant cable, and the receptacle belongs on the power-unit side; these are electrical connectors, not hydraulic hose couplers. Lower the trailer fully and disconnect all electrical sources before opening either connector. This prevents unintended electrical operation while conductors and terminals are exposed.
Control rotation instead of loading the wires
Mate the connectors and use the locating key to resist connector-body rotation while loosening or tightening the backshells. Letting the body rotate can twist conductors, pull at screw connections and damage insulation. Slide the cable nut, clamping ring and backshell onto the cable before assembling conductors so the hardware can be installed without disturbing completed terminations.
Preparation and diagram-based termination
For the documented 395-CK001 kit, remove 1-1/2 inches of cable jacket and strip 3/8 inch of insulation from each red, green, black and white wire. Use the manual’s Figure 2 for the actual wire-to-screw mapping and its specified 1/8-inch precision flat screwdriver; no numerical screw torque is given. Stop if connector identity or the diagram is unavailable, and restore power only after assembly is complete and the trailer is safe for a controlled function check.
Step-by-Step Procedure

| Individual conductor strip length | 3/8 inch |
| Wire-screw tool | 1/8-inch precision flat screwdriver |
Diagnostic Chart
| Symptom | Check | Spec / Expected | Likely cause & fix |
|---|---|---|---|
| Connector body turns or conductors begin twisting during backshell service. | Keep power disconnected; mate the pin connector and receptacle and confirm that the locating key controls body rotation. | Control connector rotation during both backshell removal and reassembly; do not use the wires to resist rotation. | Backshell turning force is being transmitted into the conductors rather than restrained through the mated connector bodies. Basis: How-to-disassemble-Quick-Disconnect.pdf |
| Prepared cable does not match the documented kit instructions. | Confirm the installed connector is the documented kit, then measure jacket removal and each conductor’s stripped length. | 395-CK001: cable jacket removal is 1-1/2 inches; individual conductor strip length is 3/8 inch. | Cable preparation was estimated or copied from a different connector procedure. Basis: How-to-disassemble-Quick-Disconnect.pdf |
| Wire assignments are uncertain or the pendant operates incorrectly after service. | Stop operation, lower the trailer safely and disconnect all electrical sources before inspecting. Confirm connector identity and compare every wire assignment with the kit’s Figure 2. | Pin connector is pendant-cable side; receptacle is power-unit side. Stop if the diagram or connector identity is unavailable. | The connector sides may have been misidentified, or assignments may have been assumed from another KTI receiver. Basis: How-to-disassemble-Quick-Disconnect.pdf |
| A conductor has cut strands, damaged insulation or stray strands at its terminal. | With power disconnected, inspect jacket removal, stripped conductors and terminal entry before closing the connector. | No damaged insulation, cut strands or stray strands bridging conductive parts. | Aggressive stripping or poor strand placement can weaken the conductor, increase connection resistance or create a short circuit.

Common Bay Mistakes
- ✕ Treating these electrical connectors as hydraulic hose couplers.
- ✕ Turning the backshell while allowing the connector body to twist the wires.
- ✕ Copying another KTI receiver’s wire colors or terminal assignments.
- ✕ Guessing screw torque when the sheet provides no numerical value.
