Figure 2-3 Horn & Strobe Connector
To install the wiring for the horn or strobe, disconnect the connector from the header on the PCB. Strip the
insulation of each wire back approximately 0.25 in. (6 mm), insert the bare wire into the terminal and tighten
the screw clamp. Ensure that the wire cannot easily be pulled from the connector.
When all wires are connected, seat the modular connector into the PCB header; ensure that the latch engages.
Refer to Table 2-6 for signals, connector and terminal assignment for the horn and strobe.
