What circuit is on pin 1 of the transmission connector?

Pin 1 is SSE, and its connector color is GREEN.

Which pins are used for the transmission fluid temperature (TFT) sensor?

Pin 4 is TFT SIGRTN and pin 5 is TFT; both connectors are BLACK.

What connector colors are used for the shift solenoids?

SSA is WHITE, SSB is BLACK, SSC is WHITE (with SSC GROUND also WHITE), SSD is BLUE (SSD GROUND also BLUE), and SSE is GREEN (SSE GROUND also GREEN).

Which pins are ground circuits?

Pin 10 is SSE GROUND, pin 11 is SSC GROUND, and pin 12 is SSD GROUND.

What is on pins 2 and 7?

Both pin 2 and pin 7 are PCA circuits with BLACK connectors.

This document is a wiring/connector diagram for an automatic transmission internal harness, uploaded as applying to a 2003 Ford Focus automatic transmission. The upper portion is a line drawing showing a multi-pin bulkhead-style transmission connector with nine pin positions identified by circled callout numbers (1 through 9), with wiring routed to several two-terminal solenoid connectors inside the transmission. Each solenoid connector is labeled with callout number pairs (10/1, 2/7, 11/3, 12/9, 4/5) or single callouts (6, 8), and one circuit is shown grounded via a ground symbol. The lower portion is a three-column table listing pin number, circuit function, and connector color for twelve pins: SSE (green), PCA (black), SSC (white), TFT SIGRTN (black), TFT (black), SSA (white), PCA (black), SSB (black), SSD (blue), SSE GROUND (green), SSC GROUND (white), and SSD GROUND (blue). A reader can use this document to identify which transmission connector pin corresponds to each shift solenoid (SSA-SSE), the pressure control solenoid (PCA), and the transmission fluid temperature (TFT) sensor, along with the color of each solenoid's connector, useful for diagnosing solenoid circuits or testing continuity at the transmission harness connector.
