What is the pinout of the C342 compass/outside air temperature module connector on a 1996 Ford Explorer?

C342 (black): Pin 1 not used; Pin 2 = 57 (BK) Ground; Pin 3 = 1003 (GY/Y) Power (Hot in Run); Pin 4 = 679 (GY/BK) Vehicle Speed Input; Pin 5 = 705 (LG/O) Battery Saver Input; Pin 6 = 53 (BK/LB) Courtesy Lamp Input; Pin 7 not used; Pin 8 = 19 (LB/R) Instrument Illumination Input; Pin 9 = 233 (DB/Y) Ambient Temperature Sensor Feed; Pin 10 = 234 (DB/W) Ambient Temperature Sensor Return.

Which fuse powers the 96 Explorer compass/outside air temperature module?

Fuse 10, a 7.5A fuse in the interior fuse panel (hot in run), feeding circuit 1003 (GY/Y). See power distribution, page 13-7.

What is the part number of the outside air temperature sensor?

The diagram lists the outside air temperature sensor as F87Z-12A647-AA.

What wire colors connect the outside air temperature sensor?

Circuit 234 (DB/W, sensor return) and circuit 233 (DB/Y, sensor feed), running through connectors C267F/C267M, C212M/C212F, C146F/C146M, and C194 to the sensor.

How is the module grounded?

Through circuit 57 (BK) on pin 2, via splice S202 to ground G204 (see grounds, page 10-8).

This document is a wiring diagram (EVTM-style) for the compass/outside air temperature module in a 1996 Ford Explorer, labeled "96 Explorer." The schematic shows the module powered by circuit 1003 (GY/Y) through fuse 10 (7.5A) in the interior fuse panel (hot in run), with ground via circuit 57 (BK) through splice S202 to ground G204. Inputs include instrument illumination on circuit 19 (LB/R), courtesy lamps on circuits 705 (LG/O) and 53 (BK/LB), and vehicle speed input on circuit 679 (GY/BK) from the engine controls. The ambient temperature sensor (part number F87Z-12A647-AA) connects via circuits 233 (DB/Y) and 234 (DB/W) through inline connectors C267F/M, C212M/F, C146F/M, and C194. The lower portion of the page shows the physical pinout of connector C342 (black), a 10-pin connector, with a table listing each pin's circuit number, wire color, and function: pins 1 and 7 not used; pin 2 ground; pin 3 power; pin 4 vehicle speed input; pin 5 battery saver input; pin 6 courtesy lamp input; pin 8 instrument illumination input; pins 9 and 10 ambient temperature sensor feed and return. Cross-references point to power distribution (page 13-7), grounds (page 10-8), courtesy lamps (89-1, 89-2), and engine controls (24-4, 25-4).
