WARNING
Do not exceed product rating or tow vehicle lamp load rating, whichever is lower.
Be sure not to lay tools a crossed the positive (typically noted with red covers or a red '+'
symbol). This can cause a ground to short causing sparks, and / or electrical shocks.
The battery connection must be fuse-protected, 10-amp max. Exceeding
the product rating can cause loss of warranty, overheating and potential fire.
Maintenance
Periodic inspection of all wires and connections should be performed
to ensure there is no visible damage or loose connections.
Electrical Ratings
Signal circuits 5.0-amps per side
Tail / Running Circuits 7.5-amps total
Check vehicle owner's manual or contact
the vehicle manufacturer for more information.

NOTICE
Before you begin installation, read all instructions thoroughly.
Proper tools will improve the quality of installation and reduce the time required.
All steps must be followed to ensure the product will function properly. Once installed,
test for proper function by using a test light or connecting a properly wired trailer.
Level of Difficulty
Easy
Installation difficulty levels are based on time
and effort involved and may vary depending on
the installer level of expertise, condition of the
vehicle and proper tools and equipment.

Step 1
Locate the vehicle battery and disconnect
the negative battery terminal. Be sure to fasten
this wire down and away from the battery
while completing the installation process.
Step 3
Remove the taillight by pulling straight back.
Carefully remove the connectors, taking care
not to damage the locking tabs on the back.
Set the taillight off to the side and repeat
on the other side of the vehicle.
Step 2
Open the tailgate. Use an 8mm
socket to remove two bolts
securing the taillights in place.
Repeat on the other side of the vehicle.
56465-INS-RA • 06/22/2021 • ECN8249 • PAGE 3 OF 5
Step 4
Beginning on the driver side of the vehicle,
drop a fish wire down inside the box where
the taillight was removed. From under the
vehicle, attach the yellow wire to the fish wire
and pull up into the taillight opening. Attach
the custom wiring harness to the taillight.
Re-attach the factory harness to the taillight
and to the custom wiring harness.
How to Fishwire
A) Fish wire is a way to push or pull
an electrical wire through a blind hole.
Make sure the wire is long enough
to stick out on the other side.
Insert the fish wire through the blind
hole and locate it on the other side.
B) Use tape to secure the harness
to the fish wire and pull back up.
The fish wire or harness may get hung up on
something, if this happens you may have to
push back down, wiggle it around or twist the
wire to loosen it from what it's hung up on.
Fish wire could be anything from a cut-up wire
hanger, stiff wire, rope or string depending on
what is needed for the installation.

Step 5
Route the green wire over to the passenger side. Zip tie as needed to the rear bumper.
Repeat step 4 using the green wire.
Adhere the black converter box using the provided double-sided tape.
Secure any loose wires with the provided cable ties.
Step 6
Locate a grounding point such as an existing
screw or bolt in the frame of the vehicle or drill
a 3/32"pilot hole. The area should be free from
rust, dirt, and paint (abrasive pad/paper to
remove rust and paint). Secure the white ground
wire with the ring terminal on the existing
fastener or with the provided ground screw.
CAUTION
Check for miscellaneous items that may be
hidden behind or under any surface before
drilling to avoid damage and/or personal injury
NOTICE
Once the custom wiring harness is installed,
verify that the harness is functioning by
attaching the 4-flat to any vehicle with
functioning trailer lights. The taillights
on the tow vehicle should function along
with the taillights on the towing vehicle.

Step 8
Route the black power wire from the vehicle battery as shown on the last page of this manual.
Reinstall all items removed during install. If it was disconnected at the beginning of the installation,
reconnect the negative battery terminal. Install the provided 4-flat dust cover to help prevent corrosion.
Step 7
Route the 4-flat along the rear bumper and zip tie
as needed. Mount the 4-flat close to the receiver tube.
