ECU Connections – Airo 5
The connections on the ECU are made so that plugging the wrong connector
in is difficult due to the orientation points inside the connectors. If you pay
attention to these, then each plug will be a nice push fit, and no force should
be required.
Figure XXV shows the correct connections and their wire colours:
•
X1: Air motor (red, yellow, brown and blue)
•
X2: Glow plug/flame sensor (brown and yellow)
•
X3: Overheat sensor (2 x blue)
•
X4: Fuel pump (2 x black)
•
X5: Temperature sensor (brown and blue/purple)
•
X6: Convector Motor (empty)
•
X7: Main wiring harness (bulk)
