For best results, the IR transmitter must be installed as shown in figure 1
with the LEDs pointing towards the rear of the vehicle.
Audio input can be connected to either a low-level fixed audio output or a
variable level audio output (such as a speaker or headphone output). If it is
connected to a low-level output, only the volume control on the headphones
needs to be adjusted to control volume level. If connected to a variable level
outputs, then the volume adjustment needs to be accomplished at both the
sources and at the headphones.

1. Using two dual RCA (M/M) cables (not supplied—length to be determined
by installation requirements), connect one end of each to the Red and White
RCA jacks. Connect the other ends to the channel A and channel B to each
of the low level signal sources (A and B).
2. Connect pin 4 of the channel A harnness (Black wire, negative) to the
ground of the vehicle.
3. Connect pin 5 of the channel A harness (Red wire, +12 volt) to the ignition source. This is an ignition wire that provides +12V when the ignition key
is turned on.
