Which is the output line of the Accord mainframe?

The output line of the Accord host ecu is the two-way contact on the right.

The main output ports of Accord ECU are aimed at the ignition coil of oil pump and some active sensor series, which need to supply power to relays in many positions to form control, and to supply power to similar crankshaft position sensors, valve position sensors and throttle air flow sensors to form a closed-loop signal system to work normally. These sensors and relays are the outputs of ECU.

Among the three rows of ECU wiring, the right two rows mainly control these. Judging from the binding of the harnesses, these two harnesses are the main output lines of the ECU, which are responsible for the normal running and normal starting of the vehicle. The other auxiliary lines are some auxiliary systems, which are not so important, and can operate normally even if the vehicle is not connected.

Therefore, the output lines of the Accord's main engine ECU are the rightmost two of the three lines.
