Frequently asked questions

What is the 2-way Lucar connector used for?
The 2-way Lucar connector joins two wires end-to-end within the loom using insulated blade (Lucar) terminals. It's a genuine Land Rover part (RTC603) with a double sleeve, one insulating cover over each terminal, giving a serviceable in-line joint you can disconnect for repairs.
Where is this connector used on the vehicle?
This Lucar connector is used throughout the wiring harness wherever a serviceable two-way joint is needed. It typically fits older Land Rovers including the Series 1, Series 2 and 3, Range Rover Classic and Defender up to 2016, where Lucar blade terminals were standard.
What does the double sleeve, 2-way design mean?
Double sleeve means each of the two terminals in this loom connector has its own insulating cover, and 2-way means it joins two wires. That sets it apart from single-way or uninsulated blade terminals, so confirm you need an insulated two-wire harness joint before ordering.
