Module Pins

The ECU module has five connections, which are (from left to right) Ignition, Injection, Main Engine, Panel, and Exhaust. The plugs are keyed and colored so that same size plugs cannot be plugged into each other. Pin numberings for each are shown below.

Ignition Connector - 8 Pins

3 Coil 3 -
4 Coil + (all coils)
5 Shield
6 Coil 4 -
7 Coil 5 -
8 Coil 6 -

Main Engine Connector - 23 Pins

2 Oil Thermistor – (2)
3 Throttle + (4)
4 Throttle – (1)
5 Throttle position 1 (6)
6 Throttle position 2 (5)
7 MPU TDC+ / Hall (*)
8 MPU TDC- (*)
9 Coolant Thermistor + (1)
10 Coolant Thermistor – (2)
11 DPV A (A)
12 DPV D (D)
13 Solenoid +
14 Throttle pot ground (*)

20 DPV C (C)
21 Motor pot 5V (*)
22 Flywheel MPU + (A)
23 Flywheel MPU – (B)

*These connections at the sensor vary numbering by engine or branch to multiple locations. See engine harness drawing.

Panel Connector - 23 pins

This is the black 23 pin connector

(Physical pin layout the same as the image in main engine section above)
