NOTE B: FOR SPEEDOMETERS OR TACHOMETERS WITH A SINGLE SIGNAL INPUT TERMINAL, EITHER ONE OF THE TWO SIGNAL OUTPUT LINES FROM THE ECM CAN BE USED. LEAVE THE REMAINING LINE DISCONNECTED, DO NOT CONNECT TO GROUND.NOTE C: "SINGLE" WINDING MAGNETIC PICKUP SENSOR RECOMMENDED.NOTE D: THESE CONNECTIONS ARE UNSWITCHED, DIRECT CONNECTION TO THE BATTERY IS NOT REQUIRED.NOTE E: THE ECM SPEEDOMETER AND TACHOMETER OUTPUT SIGNAL LINE VOLTAGES ARE ZERO-CROSSING SQUARE WAVES. THE SPEEDOMETER SIGNALS AT J1-37 AND J1-36 ARE COMPLEMENTS OF EACH OTHER. THE TACHOMETER SIGNALS AT J1-38 AND J1-39 ARE COMPLEMENTS OF EACH OTHER. MAXIMUM SIGNAL AMPLITUDE OF J1-36, J1-37, J1-38, AND J1-39 IS +/- 10 VOLTS. AMPLITUDE WILL BE +/- 5 VOLTS OR GREATER IF LOAD CURRENT IS LESS THAN 4mA.NOTE F: IF AN ELECTRONIC SIGNAL IS PROVIDED IN PLACE OF A PASSIVE MAGNETIC SENSOR, CONNECT THE ELECTRONIC SIGNAL INPUT TO THE +SIGNAL PIN, THE -SIGNAL PIN SHOULD NOT BE CONNECTED OR GROUNDED WITH ELECTRONIC SIGNAL INPUTS.NOTE G: WIRE NUMBER 386 IS FOR AIR SHUTOFF AND IS SPECIFIC TO HARNESS 243-2321. WIRE NUMBERS G856 AND G857 ARE FOR THE TIMING CALIBRATION(TC) PROBE AND ARE SPECIFIC TO HARNESSES 243-2321 AND 248-2433.NOTE H: ONLY APPLIES TO ENGINES WITH AIR SHUTOFF OPTION.NOTE Y: IF MAIN HARNESS 263-9001 OR 243-2321, INTERNAL HARNESS C1 CONNECTOR 3E8969 WILL BE USED. IF MAIN HARNESS 248-4233 OR 243-1069, INTERNAL HARNESS C1 CONNECTOR 262-6073 WILL BE USED.NOTE X: USE KIT 156-7106 WHEN REPLACING CONNECTOR 153-9693. REFER TO REHS1809 FOR REPAIR AND INSTALLATION DETAILS.NOTE Z: THE CONNECTOR ON THIS SCHEMATIC IS BLACK AND CONNECTS DIRECTLY TO SERVICE TOOL CABLE 157-4829. THE DIAGNOSTIC CONNECTOR NOT SHOWN HAS +BATTERY ON PIN (A) AND -BATTERY ON PIN (B). THIS CONNECTOR IS GRAY AND CONNECTS TO SERVICE TOOL CABLE 139-4166.
