RS232 COMS: TX(ECU10) to TIP, RX(ECU29) to RING, DIGGND(ECU46) to SLEEVE on female 6.35mm jack is the std Pectel wiring.
COIL: Center is +12V, left is Coil A (cyl 1 & 4) and goes to IGN1(ECU19) and right is Coil B (cyl 2 and 3) and goes to IGN2(ECU55). Set firing sequence (ignition channel mapping under ignition coil config in the hardware menu) to 1:SPARK_1, 2:WASTE_2, 3:WASTE_1, 4:SPARK_2 and coil mode to Normal.
Connect +12V to the WI relay's coil, and the ground side of the relay's coil to PWM6(ECU21). NB: PWM5(ECU45) and PWM6(ECU21) are low current, OK for relay or tacho drive or a gear shift LED. All PWM output are ground side.
