To begin, plug 2 cable harnesses into your Saleae Logic Analyzer. Note that the arrow on the harness connector should be facing up and to the left (toward the ‘S’ in Saleae on your Logic Analyzer). While the colors of the wires do not ultimately matter, it can be helpful to have them line up with the resistor color code (from left to right): black, brown, red, orange, yellow, green, blue, violet.
