the  10-amp  fuse  must  be  within  six  inches  of  the  
positive terminal. if the 10-amp fuse is farther than 
six  inches,  a  short  circuit  may  cause  significant 
damage to the towed vehicle’s electrical system, an 
electrical fire, or other consequential, non-warranty 
damage.

  4.

  Now, connect the remaining wire at the break away 

switch to either one of the two wires extending from the 
top of the solenoid valve on the air reservoir (Figures 
8  and  10).  If  necessary,  use  the  remaining  length  of 
14-gauge  black  wire  to  reach  the  top  of  the  solenoid 
valve. As before, strip the ends of the wires before con-
necting them with the supplied blue butt connectors. 
 

  Where appropriate, use one or more of the included 

wire ties to secure the wire in place.

 

5.

  Crimp the smaller (#10) ring terminal onto the end 

of  the  remaining  wire  extending  from  the  top  of  the 
solenoid valve, and attach the ring terminal to any good 
chassis ground. (If necessary, use another butt connec-
tor, and any remaining 14-gauge black wire, to extend 
the length of the ground wire.)

 

6.

  If the battery must be disconnected for towing, install 

a battery switch to the positive battery cable, as shown 
in Figure 9. Connect the stop light switch wiring to the 
battery switch.

continued from preceding page

765) has been installed, follow the instructions included 
with the kit.

  1.

  Using one of the blue butt connectors, attach one 

end  of  the  supplied  length  of  14-gauge  black  wire  to 
the end of either one of the two wires extending from 
the break away switch. (If necessary, strip ¼" to 3/8" of 
insulation from the end of the wires before connecting 
them.) 
 

  Next, route the wire to the positive terminal on the 

towed  vehicle’s  battery  (Figure  8),  avoiding  moving 
parts,  sharp  edges  or  “hot”  components  such  as  the 
engine or exhaust system. Where appropriate, use one 
or more of the included wire ties to secure the wire in 
place.

 

2.

  Cut the wire and strip ¼" to 3/8" of insulation from 

the  end  of  the  wire.  Crimp  either  end  of  the  supplied 
yellow 10-amp fuse onto the end of the wire. Strip the 
insulation from one end of the remaining length of wire; 
crimp the other end of the fuse onto the wire.

 

3.

  If necessary, cut the wire again, leaving no more 

than six inches, and strip ¼" to 3/8" of insulation from 
the end of the wire. Crimp the larger (3/8") ring terminal 
onto the end of the wire, and attach the ring terminal to 
the positive terminal on the towed vehicle’s battery.

  in order to prevent damage from a short circuit,
