Here is the pinout of the 5 pin plug on the V157 flapper motor for a CBEA engine. CJAA is likely the same:
Pin 1 goes to ECU Terminal 10 and terminal 1 of the cam position sensor
Pin 2 goes directly to ECU Terminal 27
Pin 3 is ground and goes to ECU Terminal 51 and terminal 3 of the cam position sensor
Pin 4 goes directly to ECU Terminal 35
Pin 5 goes directly to ECU Terminal 50
1>>10 Yellow/grey stripe
2>>27 Lilac/black stripe
3>>51 Brown/green stripe
4>>35 Brown/green stripe (weird to have a duplicate color)
5>>50 Red/green stripe
So, set your Multimeter for Continuity and listen for beeps or if you only have an Ohms setting then look for 1.5 Ohms or less of resistance. You can also check for continuity on lines 4 and 5 to chassis ground only after you have unplugged the ECU.
