<THESE INSTRUCTIONS MUST BE GIVEN TO THE END USER>

NOTICE: Installation of Stealth products may or may not require the addition of a wiring harness to the vehicle.

• The Rack Receiver only product does not require adding a wiring harness.

• The Rack Receiver plus Tow Kit requires the addition of a wiring harness that is compatible with the vehicle's wiring.
Depending on the vehicle, the harness will be one of two types, “Active” or “Passive.” The wiring section of the instructions will indicate which
wiring harness style is being used and how to install it.

• The Active Harness plugs into the vehicle's wiring so that the vehicle's computer can communicate with the trailer wiring. This allows certain functions
such as cameras or backup alarms to continue to operate as designed. Some active harnesses require reprogramming of the vehicle's computer
before the trailer wiring is functional. For BMW vehicles that need programming, Stealth provides this service remotely. Refer to the Active Harness
section of the instructions to determine if programming is required for this install. This programming must be taken into account when planning
the timing of the Stealth product install. The remote BMW programming needs to be scheduled approximately 1 week in advance.

• The Passive Harness is independent of the vehicle's computer and communication system. The module of the harness
is powered directly from the battery rather than the vehicle's wiring harness. The module monitors the output signals
from the vehicle's lights. It then powers and activates the trailer lighting accordingly.
INSTALLATION NOTE: In most instances, these instructions will only outline disassembly of vehicle components.
Re-installation of components will require the installer to retain vehicle hardware and work through disassembly instructions in reverse order.
When installation is complete, double check that all vehicle components have been replaced and are secured.

NOTICE: Installation of hitch requires removal of vehicle parts and interaction with vehicular electronics. Before
installation, check the condition of body panels and note any locations where panels are not flush. Check the
electronic functions of the vehicle, such as: headlights, taillights, turn signals, cameras, backup sensors, Parking
Distance Controller (PDC), foot activated cargo access, etc. It is the responsibility of the installer to restore the
fit and function of the vehicle.

NOTICE: If installing an active wiring harness, your vehicle must be programmed.

Arrangements can be made with Code My Car (585-496-4648). Please allow at least a week to make programming
arrangements. Programming will require your vehicle to be connected to a computer and an internet connection. Note:
A programming code is affixed to the control module and the programming cord which will be needed when
contacting Code My Car. Additional programming changes may be available at time of programming. Arrangements
can be made when contacting Code My Car.

• The passive wiring kits
BOX
use a
control module to manage the
functions of the trailer lighting.
The module has an “input” side that
receives power from the vehicle's
battery and signals from the
vehicle's taillights. The “output” side of the module delivers this information to the 7-way plug, see passive harness
diagram. The control module is connected to the vehicle's battery and taillight wiring as outlined in the next
steps.
• The active wiring kits use a BMW computer control module to manage the functions of the trailer lighting. The
module must be “programmed” before it will be functional. The module will connect to the vehicle through an
included wire harness. The harness has an “input” side that receives power and signals from the vehicle's
electronic systems. The “output” side of the harness delivers this information to the 7-way plug. The harness
and computer module installation are outlined in the next steps.

TEST 7-WAY HARNESS WIRING
65. While everything is still accessible, you should
test the wiring to make sure everything is
connected properly and in working order. If
installing the passive wiring harness, replace
the 20 Amp fuse into the fuse holder located
near the battery.

NOTICE: Most Active harness installations will

require programming before testing can be
completed. Testing Active wiring harness
installations with a multimeter or LED tester may
not work. Some vehicles may need to “sense”
the current being used by the plug to function. After
programming is complete, use an incandescent light
testing device or trailer to test in these specific
cases.

NOTE: Taillights will need to be temporarily plugged in during testing.

• Start by connecting the multimeter negative probe to the ground blade on the 7-way
receptacle.
• Next, connect the multimeter positive probe to the power blade on the 7-way receptacle
and check for 12 volts.
• Once that is confirmed, move the positive probe to the left turn blade on the 7-way
receptacle and check for 12 volts when the vehicle left turn blinker is active. You should see it pulse.

• Next, move the positive probe to the right turn blade and check for 12 volts when the right turn blinker is active. You
should see it pulse.
• Next, move the positive probe to the marker/taillights. With the vehicle lights on you
should see 12 volts constant.
• Lastly, with the brake depressed, move the positive probe to the left turn blade where you should see 12 volts constant.
Move the probe to the right turn blade where you should also see 12 volts constant.

COMPLETE WIRING KIT INSTALLATION

66. Attach the mounting bracket and 7-
way housing to the Stealth hitch
frame as shown.
Secure harness to Stealth hitch
frame with cable ties.

67. Secure all wires and wiring

FINAL VEHICLE EXAMINATION
75. Examine the body panels to ensure that they are in a pre-installation condition. Test the
electronic functions of the vehicle. Correct any inconsistencies.
76. Ensure that hitch components work properly.
• Verify that the lock works correctly. Push in the safety lock on the latch block then unlock
with key. The lock should slide back out with the key when unlocked.
• Verify that each accessory can be installed correctly. Use the following steps to install and
remove each accessory that will be used with the hitch. (Rack Receiver and Ball Mount if
purchased.)
1. Prepare latching mechanism. Turn handle clockwise if needed.
2. Firmly insert “post” of accessory into latch block until handle releases indicating
that the accessory is latched.
3. Push in the safety locking pin until it fully engages. The locking pin prevents the handle
from turning when pushed in, and confirms that the block is securely latched onto
the accessory. The safety locking pin will not depress if the accessory is not fully latched.

4. Use key to release safety locking pin.

5. While holding on to the accessory, rotate handle clockwise to release and remove
The accessory.
• Verify that no part of the accessories come into contact with the body of the vehicle.

PRODUCT USE AND MAINTENANCE

NOTICE: If the hitch is being installed by a professional, the installer is responsible for
training the end user in the use and maintenance of the product.
• Accessory installation procedure:
1. Prepare latching mechanism. Turn handle clockwise if needed.
2. Firmly insert “post” of accessory into latch block until handle spins counter-
clockwise indicating that the accessory is latched.
3. Always depress the safety locking pin and check that it has fully engaged.
• Never use any accessory with the safety lock disengaged. Until the safety locking pin is
engaged, the handle is able to turn. A fully engaged safety locking pin is confirmation that the
accessory is properly latched into the latch block.
• Never use the rack receiver for towing. The rack receiver accessory is only to be used with
payload carrying products, such as bike racks or luggage racks.
• Before each use, give the post of the accessory a light coating of lithium based grease.
• Before each use, inspect the hitch to ensure that all bolted connections are secure and that no cracks or
damage are present. Do not tow with the hitch if cracks or damage outside of normal wear is found.

• Remove the Stealth accessories from the latch block after each use. Do not leave
accessories plugged in for extended periods of time.
