  Next, remove the break away pin (Figure 7) at the 

front  of  the  break  away  switch.  The  air  cylinder  and 
pedal clamp will extend, confirming the proper opera-
tion of the break away system.
 

  To retract the air cylinder and pedal clamp, recon-

nect the break away pin.
 

  Before towing, charge the break away air reservoir, 

as described above.

 

7.

  Confirm the proper operation of the towed vehicle’s 

brake lights and turn signals — 

 

 

A.

  Depress  the  motorhome  brake  pedal;  confirm 

that the towed vehicle’s brake lights illuminate. Activate 
both  of  the  motorhome  turn  signals;  confirm  that  the 
towed vehicle’s turn signals activate. 
 

  If the towed vehicle’s brake lights and turn signals 

do  not  operate  in  tandem  with  the  motorhome’s,  you 
must  install  a  non-intrusive  lighting  system  or  re-wire 
the towed vehicle. See “Brake light solutions.”

 

 

b.

  With  one  of  the  motorhome  turn  signals  acti-

vated,  depress  the  motorhome  brake  pedal.  Confirm 
that  the  towed  vehicle’s  brake  lights  and  turn  signal 
both illuminate.
 

  If the towed vehicle’s brake lights override the turn 

signal, you must install a non-intrusive lighting system 
or  re-wire  the  towed  vehicle.  See  “Brake  light  solu-
tions.”

  by law, a towed vehicle’s turn signals and brake 
lights must operate in tandem with the motorhome’s, 
as described above. if they do not, drivers behind 
the towed vehicle will not be alerted when the mo-
torhome  stops  or  turns,  which  may  cause  an  ac-
cident.
  if the towed vehicle’s brake lights and turn sig-
nals do not operate in tandem with the motorhome’s, 
either install a non-intrusive lighting system or re-
wire  the  towed  vehicle  according  to  the  next  sec-
tion, “brake light solutions.” then, test for proper 
operation, as described in step 6, above.
  failure  to  follow  these  instructions  may  cause 
property damage, personal injury or even death.
