Land Rover Gear Selector
General Information
There are a wide variety of subtly-different part numbers for the assorted gear selectors found in various Land Rover/Jaguar vehicles over the years. It's not particularly easy to differentiate them just using part numbers, so for the sake of this article, the earlier units (2010-2015) will be referred to as "gen 1" and later units (2013+) as "gen 2" - this doesn't denote any OEM markings, it's simply a way to differentiate them here.
Part numbers for sourcing
At a glance, there are some conventions that the part numbering (p/n) seems to follow:
- gen 1 (and some gen 2) units have an 11-charcter p/n format: XXXX-XXXXX-XX (e.g. AW93-7E453-BD), and just show one part number in this format on the label.
- other (later?) gen 2 units have the 11-character p/n format: XXXX-XXXXX-XX (e.g. HPLA-7E453-CA) as well as two 12-character versions (e.g. HPLA-14C559-CA & HPLA-14C561-CA ) on the same label.
- the middle sequence always seems to be "7E453" on gen 1 units, and gen 2 units will have this sequence as well as "14C559" and "14C561".
Hardware Variants
Gen 1
The gen 1 is a somewhat elaborate unit with a motorized gear selector knob and indicators, assorted driving mode pushbuttons, as well as an Electric Park Brake (EPB) actuation switch. Some units also include a Start/Stop pushbutton. Gear selection options are P R N D S. Housings are polished metal with dark buttons, and are quite long overall.
Note: selecting S requires pushing the knob down while turning the selector from D.

Connector
The 22-way plug on gen 1 units is TE 0-1411226-1 (or possibly TE 1-1419158-7)
Control Scheme
An Arduino sketch to control the selector knob and indicators (as well as a host of CAN logs) can be found here: https://github.com/Tom-evnut/Land-Rover-Gearknob/tree/main/Can%20Logs%20Gen1%20Knob
Note: the actuation (raising and lowering) of the selector knob is controlled by the IGN pin on gen 1 units.
Gen 2
The gen 2 is a much simpler unit with only a motorized gear selector knob and indicators. Gear selection options are P R N D S. Housings are black plastic or polished metal, with some variation on the styling of this surrounding trim.
Note: selecting S requires pushing the knob down while turning the selector from D.

Connector
The 12-way plug on gen 2 units is TE1452015-2
Control Scheme
An Arduino sketch to control the selector knob and indicators (as well as a host of CAN logs) can be found here: https://github.com/Tom-evnut/Land-Rover-Gearknob/tree/main/Can%20Logs%20Gen2%20Knob
Note: on early gen 2 units, the actuation (raising and lowering) of the selector knob is controlled by the IGN pin and the unit responds to commands using ID 0x3F3. On later gen 2 units, the actuation (raising and lowering) of the selector knob is controlled by CAN commands and the unit responds to commands using ID 0x02C.
