Determine which wire is connected to which pin using a multimeter on the resistance setting.

The pins as shown in figure 4-2 are the opposite of the pins circled in red. The figure is illustrating the pins as seen on the Autosampler rather than on the connector shown.

The wire colors as determined by this test for this wire configuration are as follows: blue = bottle number, green = pulses to autosampler, brown = event mark, black = power, white = ground, red = inhibit.
