What connector is shown in this diagram?

Connector C2044, which plugs into the Remote Climate Control (RCC) Module. It has 26 pins arranged in two rows (1-13 and 14-26).

Which pins on the RCC module connector are not used?

Pins 12, 14, 16, 17, 18, 19, and 25 are marked NOT USED.

Which pins provide power and ground to the RCC module?

Pin 10 is circuit 298 (P/O), Power (Hot In Run); pin 11 is circuit 729 (R/W), Power (Hot at All Times); pin 8 is circuit 570 (BK/W), Ground; pin 15 is circuit 470 (PK/BK), Signal Return.

Which pins connect to the temperature sensors?

Pin 6 (468 BR) is the Sunload Sensor Input, pin 7 (788 R/O) is the Ambient Temperature Sensor Input, and pin 23 (790 W/O) is the In-Car Temperature Sensor Input.

What pin controls the blower speed?

Pin 24, circuit 776 (O/BK), is the Variable Blower Speed Output.

This document is a connector pinout diagram and table for connector C2044, the Remote Climate Control (RCC) Module, uploaded as applying to a 1997 Ford Taurus. It shows a 26-pin connector face view: pins 1-13 on the top row and pins 14-26 on the bottom row, with several pins (12, 14, 16-19, 25) marked as unused. Callout labels around the connector identify each circuit number and wire color code (e.g., 832 LB/PK, 833 T, 914 T/O, 915 PK/LB, 436 R/LG, 468 BR, 788 R/O, 570 BK/W, 437 Y/LG, 298 P/O, 729 R/W, 348 P on top; 470 PK/BK, 438 R/W, 249 DB/LG, 250 O, 790 W/O, 776 O/BK, 1087 O on bottom). An accompanying table lists every pin's circuit number, wire color, and function, including data bus lines, powertrain control module inputs, blend door actuator outputs and motor power, sunload/ambient/in-car temperature sensor inputs, ground, signal return, hot-in-run and hot-at-all-times power feeds, A/C clutch cycling pressure switch input, variable blower speed output, and IGN-A/C clutch. This is useful for diagnosing electronic automatic climate control (EATC) wiring problems.
