What fuse powers the instrument cluster gauges in this diagram?

The METER 15A fuse in the interior fuse panel (page 13-7), which is hot in start or run, feeds the cluster through connector C213 on circuit 41 BK/Y.

What does the inertia fuel shutoff (IFS) switch do?

Per the callout, it opens on vehicle impact to remove voltage from the fuel pump to stop the flow of gasoline. It connects at connector C426.

How does the temperature gauge get its signal?

The coolant temperature sender (connector C185) measures coolant temperature on circuit 133 BK/BL; the instrument cluster uses this to determine the position of the temperature gauge needle. The circuit routes through C249 and either C126 (manual) or C151 (automatic).

Which connectors serve the fuel pump/fuel gauge sender?

The fuel pump/fuel gauge sender connects through connectors C404 and C419, with grounds via 59 BK/R and 53 BK wires to splice S400 and grounds G105 and G400.

This document is a scanned automotive wiring diagram covering the instrument cluster fuel and temperature gauge circuits, applicable to a vehicle offered with 2.0L and 2.5L engines (consistent with a mid-1990s Ford Probe). Power feeds from the interior fuse panel (METER 15A fuse, hot in start or run, page 13-7) through connector C213 on circuit 41 BK/Y to the instrument cluster at connector C241 (12V start/run). The cluster contains the temperature gauge, voltage gauge, fuel gauge, a solid-state fuel indicator module, a low fuel indicator, and a fuel cutout indicator. The fuel pump/fuel gauge sender connects via connectors C404 and C419 with circuits 103 Y/R and BK/W, grounding through 59 BK/R and 53 BK to grounds G105 and G400 (splice S400). The coolant temperature sender (C185) feeds the temperature gauge via circuit 133 BK/BL, routing through C249 and C126 (manual) or C151 (automatic). The inertia fuel shutoff (IFS) switch at C426 opens on vehicle impact to cut voltage to the fuel pump; circuits 738 BL, 244 W/R, and 703 W/Y tie into the electronic engine controls (pages 23-1, 25-6). Callouts explain sender and IFS switch functions, and ground/power distribution page references are included.
