A21 and A22 are the ignition signal. These two wires are connected together in the wiring and
continue as one wire to the ignitor/distributor.
What needs to be done is cut these wires and connect the ends at the connector to CH1 IN and the
other ends (to the harness and distributor) to CH1 OUT.
Do not connect any other launch control channels.
Connect GND to A23 or A24 or A26.
Connect +12V to A25.
Clutch switch must connect to GND when pedal pressed.
Other Honda ECUs
Look for the ignition signal from the ECU pinout or wiring diagram.
Most often it is A20 yellow/black
A24 would be +12V when ignition ON
A9,10,22,23 GND
It is always a good idea to measure the +12V and GND with a multimeter to confirm.
