Match the Lincoln body before the logo

MKX II, Nautilus I and Navigator are separate vehicle paths. Check the body and year first, then choose the logo, finish and set on the exact product page.

Nautilus I CD539 · 2019–2023

The exact Stainless Nautilus listing identifies Nautilus I 2019–2023 and offers Front Pair or Front + Rear. A separate Lincoln logo page uses the same body path.

Open the exact product listing

Confirm Nautilus I body and year.

MKX II CD539 · 2016–2018

The MKX Stainless pages describe the second-generation CD539 path. One title says 2016+ while its description says 2016–2018; keep that difference visible.

A Lincoln or Nautilus wordmark does not establish a shared threshold. The named body and generation still control the product path.

Read the set, finish and light zones on the exact page

The Lincoln Stainless pages offer Front Pair or Front + Rear sets, COLOR, SET and STYLE selectors, and describe logo, top light bars and side-edge illumination. The Nautilus Matte PRO page has separate body-color, highlight-color and set selectors; it describes light through the lettering and lines on top while the edge and lower surface remain unlit.

Product path Product-level evidence Buying check
Nautilus Stainless FRONT or FRONT+REAR; Stainless logo, top bars and side edge are described on this page. Confirm Nautilus I body and year.
MKX II Stainless FRONT or FRONT+REAR; the MKX II page has its own logo and STYLE choices. Do not transfer the Nautilus path.
Nautilus Matte PRO COLOR BODY, COLOR HIGHLIGHT and SET; top lettering and lines illuminate, with edge and lower surface unlit. Use this page for Matte zones.

Compare Stainless and Matte on the same body path

For Nautilus I, the Stainless and Matte PRO pages are separate finish paths for the same model family. Stainless describes logo, top bars and side-edge illumination. Matte PRO uses a painted stainless upper plate with an ABS edge in the selected body color and describes top-only illumination. Keep each set and light description with its own page.

Plan the threshold and wiring route

The named Lincoln Stainless descriptions place adhesive plates on the flat painted-metal threshold and specify red positive and black negative wires to a suitable vehicle source. A door-activated circuit turns the illumination on when the door opens; wiring is routed beneath interior trim. The Matte pages also state that wiring is required, so do not describe these products as no-wiring accessories.

  1. Verify the exact model, generation and threshold before opening the adhesive.
  2. Dry-fit the selected Front Pair or Front + Rear set and check door and seal clearance.
  3. Measure the intended low-voltage circuit and confirm polarity instead of relying on wire colour alone.
  4. Route the wires beneath trim while keeping the path clear of moving and restraint components.
  5. Test illumination and door shutoff before final adhesion.

Use the measuring guide and installation guide for preparation, then follow the exact Lincoln page.
