HI BEAM INDICATOR: This wire is the power for the Blue High Beam Indicator light in the dash.
Connect this wire to the High Beam output from the dimmer switch.
RIGHT TURN INDICATOR: This wire is the power for the Green Right Turn Indicator light in the
dash. Connect this wire to the Right Turn Signal circuit.
LEFT TURN INDICATOR: This wire is the power for the Green Left Turn Indicator light in the
dash. Connect this wire to the Left Turn Signal circuit.
REVERSE CIRCUIT: This circuit has two wires that are used to power the backup lights. Connect
one of the two wires to the fuse block to provide +12V to the Reverse Circuit. Connect the other
wire to the backup lights in the rear of the car. These two wires are connected through the
engine harness to the backup light switch in the transmission.
BRAKE SWITCH: This wire provides a signal to the ECU indicating that the brakes are be applied.
Contrary to most Honda conventions, this wire supplies +12V to the ECU from the Brake Light
Switch. Connect to the output side of the Brake Light Switch. The output is the side that powers
the Brake Lights.
The MIL light (Malfunction Indicator Light) is connected to a +12V source and the wire in the
harness supplies a ground from the ECU. It will come on if there is a code. To check the codes
the SCS (Service Check Switch) wire has to be connected to ground (we usually do this with a
momentary push button switch).
