Found this on another site. Looks to be pretty accurate.
Connectors are named by the number of pin slots available whether there is a pin there or not. The pin numbering is then 1 through the highest pin slot number, in this case 8. This makes it easier to identify the pins especially when some identical connectors can have different pins missing. You also then always know what the highest pin number is.
Stock (2g) 8 pin connector wire colors:
pin 1: blue-black (output to fire cyl 2,3 coil's primary)
pin 2: brown-red (input from ECU to fire cyl 2,3)
pin 3: black (ground)
pin 4: white (tach output to ECU and gauge)
pin 5: unused
pin 6: larger black-white (+12V from ignition switch)
pin 7: black-blue (input from ECU to fire cyl 1,4)
pin 8: black-white (output to fire cyl 1,4 coil's primary but leaves coil as blue-red going to single pin "engine speed detection connector", then from there to pin 8 here as black-white)
