How many connectors does this ECU harness diagram show?

Three connectors: a 10-pin connector (pins 101–110), an 18-pin connector (pins 51–68), and a 24-pin connector (pins 1–24).

How are the pins numbered on the largest connector?

The 24-pin connector is numbered 1 through 12 on the top row and 13 through 24 on the bottom row.

Which pins are in the smallest connector?

The 10-pin connector contains pins 101–105 on the top row and 106–110 on the bottom row.

Does the diagram show wire colors or circuit functions for each pin?

No. The diagram shows only the connector shapes and pin cavity numbers; no wire colors, functions, or labels are included.

This document is a line-art diagram of the three electrical connectors on an ECU (engine control unit) wiring harness, uploaded to a 1991 Eagle Talon gallery under the filename '1g_ecu_harness.gif' (i.e., first-generation ECU harness). The diagram shows the face view of each connector with all pin cavity numbers labeled. The left connector is a 10-pin block numbered 101–105 across the top row and 106–110 across the bottom row. The middle connector is an 18-pin block numbered 51–59 on the top row and 60–68 on the bottom row. The right connector is a 24-pin block numbered 1–12 on the top row and 13–24 on the bottom row. Each connector outline includes its locking tab/keying features drawn at the top edge. No wire colors, circuit descriptions, part numbers, model years, or other text appear in the image — it serves purely as a pin-numbering reference so that a reader can identify which cavity corresponds to which ECU pin number when probing, back-probing, or repairing the ECU harness connectors. This page appears to be part of a set that also includes a MAF (mass airflow sensor) harness diagram.
