A breakout box, connected in series with wiring harness and PCM, is necessary to perform most circuit tests. References to test pin numbers found in CIRCUIT TEST steps refer to test terminals on manufacturer's breakout box. Circuit diagram at beginning of each test identifies circuit and wire colors.
