This chassis harness is the required wiring adapter when replacing older LCI leveling controllers (175226 or 67758) with the current replacement module 2020003067. The connector configuration changed between the legacy and new controllers, making this 21-foot, 6-way harness an essential part of a complete, correct upgrade -- not an optional add-on.
LCI's leveling controller 2020003067 replaced two earlier controller part numbers -- 175226 and 67758 -- across Class A motorhome hydraulic leveling systems. The replacement controller uses a different chassis connector pinout than the controllers it supersedes. Installing the 2020003067 module without swapping the chassis harness results in incorrect wiring that will prevent proper communication between the controller, hydraulic pump relay, solenoid valves, and sensor inputs.
Lippert 690235 bridges that compatibility gap. It provides the correct 6-way connector on the controller end and the correct mating connector on the chassis side, with 21 feet of harness length to accommodate routing through the coach without splicing or extending.
Mandatory when swapping controllers 175226 or 67758 to new module 2020003067
Sufficient reach for most Class A motorhome chassis installations without splicing
Matches the pinout of the LCI 2020003067 replacement controller module exactly
Genuine LCI part number 690235 -- not an aftermarket splice kit or adapter
The legacy controllers 175226 and 67758 used a connector configuration that is not directly compatible with the 2020003067 replacement module. LCI redesigned the chassis-side connector as part of the module update, which added improved diagnostic capability and updated solenoid control logic. The 690235 harness reflects that updated pinout and is the OEM-specified solution for completing the controller swap correctly.
This harness replaces the existing chassis harness between the leveling controller and the rest of the hydraulic system. It does not replace individual solenoid valve leads, pump relay wiring, or the jack position sensor harness. Verify the complete wiring path from the controller location to the pump/valve manifold before ordering -- 21 feet covers most Class A applications but may not suit heavily modified or non-standard installations.
