What wire color feeds the door courtesy lamp switches on the Ford Probe?

Wire 300 R/W (red/white) runs through splice S258 to C306 (left door courtesy lamp switch) and C307 (right door courtesy lamp switch); both switches close with the door open.

How does the low washer fluid indicator work per this diagram?

The cluster's low washer fluid indicator connects through C241 and C206 on wire 245 P to the washer fluid level switch at C133. The switch closes with low fluid level, grounding through wire 52 BK to G103, illuminating the indicator.

When does the luggage compartment lamp switch close?

The luggage compartment lamp switch closes with the liftgate open. It is fed on wire 301 R via C423, C200, S405, and C405, with ground at S400/G400 (see grounds page 10-13).

Which connectors are involved in the anti-theft portion of the door ajar circuit?

A dashed box labeled 'WITH ANTI-THEFT ONLY' shows connections through connector C204 (and C213) in the door ajar indicator circuit.

This is one page of a multi-page factory-style wiring diagram covering the instrument cluster warning indicator circuits of a Ford Probe. The diagram shows three cluster indicators: the door ajar indicator, the fasten seat belt indicator, and the low washer fluid indicator, with feed continuing from page 60-4. The door ajar circuit runs on wire 300 R/W through connectors C201, C204, C213, and splice S258 to the left (C306) and right (C307) door courtesy lamp switches, which close when a door is open; an anti-theft-only branch is noted. A related branch on 301 R feeds the luggage compartment lamp (page 89-2) through C423, C200, S405, and C405 to the luggage compartment lamp switch (closed with liftgate open), grounding at S400/G400 (grounds page 10-13). The fasten seat belt indicator connects via C240 on wire 307 BR/BK through C215, the interior fuse panel, and C213 to a solid-state output of the Central Processing Unit (CPU, pages 66-1, 66-2, 112-3), with grounds referenced on pages 10-2, 10-3, and 10-7. The low washer fluid indicator connects through C241 and C206 on wire 245 P to the washer fluid level switch at C133, which closes with low fluid, grounding via 52 BK at G103.
