See Figure 1. On FLHTPI models, the input jack for the microphone is located on the right side of the storage box. On FLHPI models, the jack is located at the back of the headlamp nacelle below the right side of the handlebar clamp shroud. See Figure 2.
On FLHPI models, an accessory switch can be found on the left side of the handlebar clamp shroud and toggles between ON and OFF. In lieu of the accessory switch, the cigarette lighter on the left side of the fairing on FLHTPI models can be used as a 12 volt power supply source.
On both FLHTPI and FLHPI models, the accessory connector (4-place Deutsch) is anchored to the upper frame cross member (under the seat at the front of the battery box).
