Safety First

This document provides all the necessary information to allow your Whelen product to be properly and safely installed.
Before beginning the installation and/or operation of your new product, the installation technician and operator must
read this manual completely. Important information is contained herein that could prevent serious injury or damage.

• Proper installation of this product requires the installer to have a good understanding of automotive electronics,
systems and procedures.

• If mounting this product requires drilling holes, the installer MUST be sure that no vehicle components or other
vital parts could be damaged by the drilling process. Check both sides of the mounting surface before drilling
begins. Also de-burr any holes and remove any metal shards or remnants. Install grommets into all wire
passage holes.

• If this manual states that this product may be mounted with suction cups, magnets, tape or Velcro®, clean the
mounting surface with a 50/50 mix of isopropyl alcohol and water and dry thoroughly.

• Do not install this product or route any wires in the deployment area of your air bag. Equipment mounted or
located in the air bag deployment area will damage or reduce the effectiveness of the air bag, or become a
projectile that could cause serious personal injury or death. Refer to your vehicle owner’s manual for the air bag
deployment area. The User/Installer assumes full responsibility to determine proper mounting location, based
on providing ultimate safety to all passengers inside the vehicle.

• For this product to operate at optimum efficiency, a good electrical connection to chassis ground must be
made. The recommended procedure requires the product ground wire to be connected directly to the NEGATIVE
(-) battery post.

• If this product uses a remote device to activate or control this product, make sure that this control is located in
an area that allows both the vehicle and the control to be operated safely in any driving condition.

• Do not attempt to activate or control this device in a hazardous driving situation.

• This product contains either strobe light(s), halogen light(s), high-intensity LEDs or a combination of these
lights. Do not stare directly into these lights. Momentary blindness and/or eye damage could result.

• Use only soap and water to clean the outer lens. Use of other chemicals could result in premature lens cracking
(crazing) and discoloration. Lenses in this condition have significantly reduced effectiveness and should be
replaced immediately. Inspect and operate this product regularly to confirm its proper operation and mounting
condition. Do not use a pressure washer to clean this product.

• It is recommended that these instructions be stored in a safe place and referred to when performing
maintenance and/or reinstallation of this product.

• FAILURE TO FOLLOW THESE SAFETY PRECAUTIONS AND INSTRUCTIONS COULD RESULT IN DAMAGE TO
THE PRODUCT OR VEHICLE AND/OR SERIOUS INJURY TO YOU AND YOUR PASSENGERS!

10mm bolts underneath (Fig. 1).

2. Locate the small cover behind the door opener, pull it off and remove
the 10mm bolt underneath.

3. There are 16 snap-in fasteners located around the door panel.
Carefully pry the door panel loose but do not remove the panel yet.

4. Behind the door opener assembly remove the two 7mm bolts.

5. Unplug the 3 connectors behind the door pull. IMPORTANT: Be sure
to remember where the connectors plug in for reassembly.

6. Remove the door lock button and pull the door panel off then unplug
the wire harness that goes to the mirror.

7. Remove the triangular cover covering the inside of the mirror base.

Preparing Wire Harness:

Because the harness cable
must be routed through a
specific, narrow and twisting
path within the mirror
assembly, it may be necessary
to temporarily extend the
length of the harness.

1. Locate the ty-wrap

2. Locate the end of the harness cable that has SOCKET-type terminals

(included) and cut the
fastener-end off.

installed on the free wires. Cut off the non-insulated wire (not used in
this application).

1. Remove the cover from the
front of the mirror assembly
(Fig. 2). (The cover snaps
off. Be careful not to brake
the snaps.)

2. Measure as shown (Fig. 3)
and mark off this location
onto the mirror assembly
cover, than drill the wire
hole through the cover
using a 3/8” drill.

3. Strongly secure the ty-wrap to the

tape. It is important to have a sufficient
length of the ty-wrap secured to the
harness (2” minimum) (Fig. 4).

Routing Harness Cable:

1. Insert the end of the ty-wrap into the
mirror assembly via the same pathway
as the mirror power cable. Push the ty-wrap through this opening
until the end of the ty-wrap sticks out of the mirror base. Pull the ty­wrap until slack in the harness is gone (Fig. 5).

2. Pull the wire through
the housing and out
the wire exit hole.
There should not be
more than 4 - 5” of
harness sticking out of
the mirror assembly.

3. Insert the end of the
harness into the 3/8”
hole you drilled in the

Fig. 5

mirror assembly cover
and snap the cover

back onto the mirror assembly.

4. Remove the ty-wrap from the harness and insert the wire terminals
into their 2 - 3 position connectors (see wiring diagrams).

Affixing Mirror-Beam™ Housing to Mirror Assembly:

Note:The following procedure requires that the mirror assembly be

no colder than 60°F (18°C).

1. Remount the mirror assembly onto the mounting bracket using the
original hardware. Make sure that neither of the harness cables are
crimped or pinched. Tighten the bolts firmly.

2. Thoroughly clean the plastic mirror assembly and the inside surface
of the Mirror-Beam housing using a 50/50 mixture of isopropyl (not
rubbing) alcohol and water. Dry completely.

3. Locate the three, 6” strips of double-sided adhesive tape (included)
and position one 6” strip on the top and one on the bottom of the
mirror assembly. When properly positioned, the tape will be centered
between the inboard and outboard ends of the mirror assembly and
the leading edge of the tape will be set back approximately 1/4” from
the rear (mirror side) edge of the assembly. After the tape is
positioned, it is important to apply pressure to the protective backing
so that the tape adheres to the surface.

4. Cut the remaining 6” length of tape in half. Using the procedure
outlined in the previous step, adhere one 3” length of tape to the
outboard end of the mirror assembly and the remaining 3” length to
the curved “neck” of the mirror assembly.

5. Fold the protective backing strips on the top, bottom and outboard
tape strips so that 1/2” to 3/4” of backing is extended over the rear
edge of the plastic mirror assembly. Trim and remove the exposed
tape. Remove the protective backing from the tape strip on the “neck”
of the mirror.

6. Mount the Mirror-Beam housing onto the mirror assembly as shown.

The housing must fully engage the mirror assembly.

Press the housing firmly onto the exposed tape on the “neck” of the
mirror.

7. The remaining protective backing strips must now be removed. The
housing must not be in contact with the backing strips. Starting with
the outboard strip, and using a small, flat blade screwdriver gently
pry the housing about 1/4” away from the mirror assembly. Carefully
pull the protective strip “tab” created in step 6, and gently remove it
completely from the tape strip. Do not allow the strip to tear while
being removed.
