OnStar FMV Mirror - Installing the Back-Up Battery (BUB); Back-Up Battery Installation Steps; Attaching Mirror and Connecting Power; Vehicle Power and Wire Connections

G Plugging-in the Back-Up Battery (BUB) ...
1. Remove Allen screw (2.5mm) from speaker door on the back of the mirror and remove door
2. Plug in the Green Battery Pack into the circuit board (make sure it locks into place).
3. Re-install the door, ensuring the wires are safely tucked into the cavity under the plastic between housing and circuit board.
4. Hand Tighten the Allen screw till snug (do not over tighten).
IMPORTANT: Be careful not to strip the hole. If you do, use a slightly larger screw, but NOT longer than the screw provided.
G Attaching the OnStar FMV Mirror & connecting power ...
Slide the mirror onto the mount or fully cured mount adaptor, being certain to FULLY seat the mirror on mount and tighten the
Torx (T20) set screw. Be sure the screw is snug (1.8N-m/16 lb-in).
• If mirror or adapter will not slide onto the wedge mount on the windshield, check for any oxidation on the mount and remove
the oxidation; apply a small amount of white lithium grease to aid in mounting.
To connect power to the OnStar FMV Mirror, follow these steps:
1. Locate the appropriate vehicle power wires in the vehicle (B+ [Battery 12V]. ACC[Accessory/switched 12V]. Gnd[Ground]).
Ensure that the VBATT and Gnd Wires are actually a constant connection and do not change when cranking, dome lights
on/off, doors open/closed, changing gears, park/reverse/drive. (Note: Power lines to dome lights in most vehicles turn off
after a period of time of the vehicle being off; do NOT connect to such lines.)
2. Route the wire harness (B+ [yellow], ACC [red] and Gnd [black]) from the mirror to the power source either along the
headliner and down the A-pillar or into the headliner.
• Secure all wires
along the entire length of the harness avoiding any audio or antenna wires/cables while making sure to
avoid sharp metal and not to interfere with any moving parts or heat sources such as steering, braking, lighting or safety
equipment (i.e. airbags, seatbelts)
3. Find and use an OEM ground connection or create a SECURE ground connection by screwing into the vehicle's metal chassis
(verify the metal is a low resistance ground point), removing any paint/coating for good connectivity.
IMPORTANT: Do not tamper with or hinder any safety equipment such as Side Curtain Airbags
(i.e. zip-tie and secure all wires near an airbag and NEVER route wires over the path of the airbag).
4. Disconnect the negative terminal of the vehicle's battery.
5. Make the appropriated wire splices and connect the B+ and ACC wires:
• Use an inline splice.
• Spread
the wire strands.
• Insert
the OnStar FMV Mirror wire and twist together.
• Solder the connection.
• Zip-tie the lines together to provide strain relief.
•
Thoroughly wrap electrical tape around the connection.
• If the provided harness is too long, bundle the wiring and make sure it does not entangle other wires or cause a rattle -OR-
cut to the appropriate length and sever the in line fuse(s) from the end and splice them (an inline fuse MUST be used).
