5. Parts installation
1) Solder the attached Transistor onto the previously removed Q301 of
P.W.B.MAIN.
6. Board wiring
1) Solder MOTOR wire and Sensor (PD701) wire, removed at Step 3,
onto P.W.B. JIG. (fig-2)
2) Solder wires from P.W.B. JIG onto respective land. (fig-3)
• Solder Motor Wire Blue of P.W.B. JIG onto COM of P.W.B. MAIN
IC401 and WHT Wire onto ORI. (fig-4)
• Solder LED (LED701) wires (RED, GLY) of P.W.B. JIG onto LED
land of P.W.B. MAIN. (fig-4)
• Solder Sensor Wire (BLK) onto HOT, located in the 32 pin of P.W.B.
MAIN IC701 and Sensor Wire (BRN) onto GND. (fig-5)
• Solder Sensor (PS701) Wire (YER, ORN, RED, BRN) of P.W.B. JIG
onto Sensor lands of P.W.B. MAIN. (fig-6)
• Solder Wire (WHT) from P.W.B. JIG, SW 202 onto S704 of P.W.B. MAIN. (fig-7)
• Solder Wire (BLK) from P.W.B. JIG, SW 203 onto S703 of P.W.B. MAIN. (fig-7)

7. Usage instructions
1) Wire the attached P.W.B. key to P.W.B. MAIN. (fig-9)
(The wire to connect P.W.B. key is not included to the unit.)
P.W.B. Key
P.W.B. MAIN
HOT
IC701 47 Pin
GND
Note: The unit is not compatible to the P.W.B. key individual movement specified for JIGKIT.
Use the control unit for proper function.
2) After wiring, connect a cable between the control unit (CDC/CT) and the PWB. FLEX
DIN jack. (fig-10)
3) Connect +12V (positive) to ACC/BACK UP wire of the connector ASSY of the control
unit and – (negative) to GROUND wire.
4) Check that the unit is functioning properly.
