STEP 1: Install the Radio Face
Plug the ribbon cable included with the Motor 4 radio body 
into the radio face. After plugging in the radio face, attach 
it to the radio body (if it is not already attached) and tighten 
with the four radio face mounting screws provided in the 
radio face box (the screws are very small and are included 
in the hardware kit included with your Motor 4 box). 
The RetroSound
®
 logo on the Motor 4 radio body should be facing 
upwards. Take care to not install the face to the body upside down.
NOTE: Optionally, the radio face can be mounted remotely up to nine feet away 
from the Motor 4 radio body using an optional Face to Body Extension Cable (sold 
separately). In some installation applications, a bracket (not included) can be used 
to mount the radio face to the radio body at an angle.
