Installation Manual

The Engager™ Break-Away System is designed to bring trailers safely to a stop by activating electric brakes, should a trailer be
disconnected while driving. This type of safety system is required in most states on trailers rated over 2000Kg GTM. The following
instructions must be precisely followed to ensure proper operations. Please read the following instructions thoroughly before installing
this product. Your trailer must have operational electric brakes before installation, and your auxiliary power wire on the tow vehicle
must be connected. Once you determine your trailer brakes work, and you verify that your auxiliary power is connected, find a secure
location on your trailer to mount the Break-Away Kit.
UNIT MUST BE FULLY CHARGED BEFORE USE
For Models 20099, 20100, 20400: If the red light illuminates when the test
button is pushed, the battery charge is low. Connect the trailer plug to the
tow vehicle so the Break-Away Kit can charge from the vehicle’s battery.
(This can only be done after kit is installed on trailer).
The amber light will illuminate indicating that the battery is charging.
(NOTE: When trailer is plugged into a tow vehicle, the yellow “Charging”
light will always remain on.)
The battery should re-charge in about twenty minutes.
For Model 20401: Check battery charge with a battery tester. If charge is
low, follow instructions above. (This kit also has a built-in charger).
MOUNTING INSTRUCTIONS:
1. Locate secure surface on trailer to mount Break-Away Kit.
2. Route screws through provided holes in the Break-Away Kit plastic
casing Use wrench and drill to secure to trailer.
3. Next, mount Break-Away Switch close enough on trailer that cable can be attached to vehicle, then follow
“Wiring Instructions”.
WIRING INSTRUCTIONS:
1. Splice one blue wire of the Break-Away Switch to the electric brake wire coming from the trailer side connector (A - see diagram on
next page). 2. Connect other blue wire of Break-Away Switch to the blue wire (labeled “Brake”) from the Break-Away box (B). (Note:
Blue wires are interchangeable on the Break-Away Switch.)
3. Splice white wire from Break-Away box to existing ground wire on trailer or ground directly to trailer frame (C).
4. Splice black wire on Break-Away box to trailer 12-Volt auxiliary power lead (D). This will charge the Break-Away battery when
vehicle is in use.
5. Test unit by pulling firmly on cable of Break-Away Switch. Battery will activate brakes. (Note: Do not use this kit as a parking brake.)
Battery should be charged and tested prior to each trailer outing.
OPERATING INSTRUCTIONS:
1. Test your Break-Away Kit before each outing as described in Step 5 of the wiring instructions.
2. Once tested, Break-Away Switch cable should be secured to vehicle bumper or frame. The cable can be attached many different
ways. Two of the most common are: (1) Pull the pin out of the Break-Away Switch (Fig. 1) and route through safety chain loop
(Fig.2), then through cable loop and reconnect pin. (2) Attach cable loop to a “D” Shackle (Fig. 3). Do not loop cable over hitch
ball, as cable may bounce off while vehicle is moving. Note: Plunger pin must be facing the rear of the vehicle directly
behind where you secure the cable on your vehicle. Any other angle may cause Break-Away Switch failure.
