Find a convenient, sturdy place on the
front of your towed vehicle to mount
the junction box 

(B). This should be

installed on the driver’s side of the
vehicle if possible. 

Clean the mounting surface and
attach the velcro patch 

(J) (Fig. 2).

Attach the junction box 

(B) to the

velcro patch 

(J) so the pin with the

ring faces forward and the wiring
harness feeds back into the engine
compartment. 

Place the mounting bracket 

(C) over

the junction box 

(B) and mark the

hole locations to be drilled and
tapped.

Remove bracket 

(C) and  junction  box (B). Drill

marked holes with a1/8" metal drill bit. 

For thin sheet metal or plastic, it may be

necessary to reinforce the plastic or thin metal to
ensure the bracket will not separate from the vehicle
when the break-away pin is pulled. If you are going
to drill through thicker metal, use hex socket head
capscrews 

(D). You will need to drill a hole using a

#25 drill bit and tap the hole using a 10-24 tap. 

Replace the junction box 

(B) and attach the

bracket 

(C) using hex socket head capscrews

(D) or sheet metal screws (G) provided (Fig. 3).

Locate a place in the firewall that will allow the
wiring harness to be fed through into the drivers’
side compartment of the towed vehicle. Use of
an existing hole would be most convenient. 

If there is no existing hole, drill a 15/32"
diameter hole through the firewall (Fig. 4 / K).
Be careful not to drill into any functional
components of the vehicle.

Starting from the junction box (Fig. 4 / B), route
