Wireless   c onnection:  
1. Connect   the   RED   wire   of   the   wireless   video   transmitter   to   the   wire   that  
supplies  power  to  the  reversing  light  (this  wire  is  energized  when  the  vehicle  
is   put   into   reverse   gear).     Measure   the   voltage   on   this   wire   to   ensure   it   is  
+12V  when  energized.     Use  a  suitable  splicing/crimp  connector  (Scotch  lock  
type)  to  connect  the  RED  wire  to  the  reversing  light  wire.     Alternatively  you  
can   strip   back   the   insulation   on   the   wire   and   solder   the   connection   making  
sure   t o   i nsulate   t he   c onnection   w ith   e lectrical   t ape   o r   h eat   s hrink   t ubing   a fter  
the   j oin   i s   m ade.  
2. Connect   the   black   wire   of   the   transmitter   to   a   suitable   ground   such   as   the  
metal   body   of   the   vehicle.     Attach   an   "O"   ring   terminal   at   the   end   of   the  
black   w ire,   a nd   s ecure   t he   w ire   t o   t he   v ehicles   c hassis.  
3. Plug   the   RCA   and   power   connections   of   the   transmitter   cable   into   the  
corresponding   s ockets   o f   t he   c amera   h arness.  
   
NOTE:   Some   cars   that   run   LED   or   computer   controlled   lighting   systems   may   not  
deliver   e nough   v oltage   t o   r un   t he   t ransmitter.     If   t he   v oltage   a t   t he   r eversing   l ight   i s  
less   than   +11   volts,   it   may   be   necessary   to   use   a   relay   to   supply   power   to   the  
transmitter.     In   t his   c ase,   t he   r eversing   l ight   i s   o nly   r equired   t o   t rigger   t he   r elay.

In   the   event   that   you   live   in   an   area   where   RF   interference   is   a   problem   (EG:   Poor  
video   signal)   you   may   need   to   change   to   a   wired   solution   using   an   RCA   cable   (Not  
included)
