For pin connector locations on the top of the mainPDM, see Fig. 1 .

For positions of individual pin-outs on the top of themain PDM, see Fig. 2 for connectors A through G(left-hand side), and Fig. 3 for connectors H and J(right-hand side).

For location of pin connectors and individual pin posi-tions on the bottom of the PDM, see Fig. 4 .

NOTE: To locate pin-outs, use this key: The firstletter indicates the connector in which the pin islocated. The second letter indicates the row ofthe connector. The third number, if present, indi-cates the number of the pin in the row, if thereis more than one. If there is only one pin in arow, this number is missing.

Examples: Pin number AF5 means connector A,row F, pin 5. Pin number BC means connectorB, pin C.

For a list of circuit breakers and relays installed inthe main and auxiliary power distribution modules,see Troubleshooting, 300 .

For a full schematic view of the PDM wiring, seeFig. 5 . For a detailed (partial) view of the PDM wiringschematic, see Fig. 6 and Fig. 7 .

To identify relay terminals, first check the type of re-lay. On micro relays, the terminals are numbered 1through 5, corresponding to the position numbers onthe schematic. On all other relays, the terminals arenumbered 30 through 87A, corresponding to posi-tions 1 through 5 as shown in Table 1 .
