Lippert Ground Control TT Lite Parts Diagram, Jacks & Touchpad Guide

Identify Lippert Ground Control TT Lite travel-trailer leveling parts by the factory callout letters in Lippert document CCD-0008629 (August 19, 2024). Unlike Ground Control 3.0 for fifth wheels, the TT Lite configuration includes a modified power tongue jack, a PSX2 front stabilizer, two short-stroke rear Hall Effect leveling jacks, and a choice of control-panel configurations.

Before ordering: compare the exact installed controller, panel connector, rear-jack side and original part-number labels. Lippert has multiple Ground Control generations and TT configurations; similar appearance does not prove interchangeability.

Compare the manufacturer’s A–V numbered components with the complete Ground Control TT Lite system layout. The diagrams help distinguish the tongue jack, PSX2 stabilizer, left and right rear jacks, controllers and touchpads. Check your installed system revision before ordering.

Rear-jack identification: Lippert identifies 342610 as the left rear and 428493 as the right rear in its TT Lite parts diagram. Check your original jack’s label, stroke, mounting and controller configuration before ordering. Do not assume that a similar Ground Control jack is interchangeable.

LCD versus compact Auto Leveling touchpad

LCD electronic pad — 421484Uses the 241316 4-pin LCD harness. Offers a display and manual/system functions through its dedicated controls. Verify its original controller before replacement.
Compact Auto pad — 425306Uses the 425585 4-pin Auto Leveling harness. For supported configurations, advanced controls can use Lippert's app and the corresponding Bluetooth controller.
Controller — 2024017807Factory identified as non-Bluetooth TT Lite controller. Do not treat it as the Bluetooth version.
Controller — 2024017806Factory identified as Bluetooth-enabled TT Lite controller. Match harnesses, controller labeling and the installed OEM configuration.

Ground Control TT Lite versus older Ground Control TT

The earlier 672136 aftermarket TT kit uses different illustrated mounting hardware and identifies a C-Jack set rather than the TT Lite's PSX2 front stabilizer. 404488 is listed as a C-Jack in that older configuration, not as the TT Lite rear Hall Effect jack. Do not use the general Ground Control system name to substitute components between these generations.
