How many pins does the Ford EEC-IV connector have?

The diagram shows a 60-pin connector, numbered 1 through 60 in three rows of 20 pins each.

How are the pins arranged on the EEC-IV connector?

Top row: pins 20 down to 1 (left to right); middle row: pins 40 down to 21 with a central mounting hole between pins 31 and 30; bottom row: pins 60 down to 41.

Where is pin 1 located on the connector?

Pin 1 is at the far right end of the top row as drawn in this diagram.

Does this diagram list what each pin does?

No. It only shows the pin numbering layout of the 60-pin connector; there are no circuit functions, wire colors, or signal names shown.

This image is a simple graphical pinout reference for a 60-pin Ford EEC-IV engine computer (ECM/PCM) connector, uploaded to a 1990 Ford Bronco gallery. The drawing shows the connector body face-on with three horizontal rows of 20 pin cavities each, numbered 1 through 60. The top row runs from pin 20 on the left to pin 1 on the right; the middle row runs from pin 40 on the left to pin 21 on the right, with a central round mounting-bolt hole between pins 31 and 30; the bottom row runs from pin 60 on the left to pin 41 on the right. Pin numbers alternate in color (black and red) presumably for readability, and the connector outline includes two mounting tabs at the bottom. The diagram contains no legend, wire colors, circuit functions, or part numbers — it serves purely as a pin-numbering orientation map so a user probing or back-probing the EEC-IV harness connector can identify which cavity corresponds to which pin number when used alongside a separate pinout/function table (such as the companion '87-95 Speed Density Pin Out Schematic' in the same album).
