Hi-tech Mirrors


With convenience and safety features like auto-dimmers, proximity sensors, and home links to operate garage doors; mirrors have become a critical and technologically advanced amenity within a car. Despite their small size, rear and side-view mirrors can host any number of parts, pins, and PCBs.



Considerably one of the most vital elements in a vehicle, lights illuminate the road ahead as well as license plates and car interiors. Some of these are activated manually while others, like brake lights, are intertwined with mechanical and electrical components.

Sensors & Safety


Water-in-fuel, check engine light, crankshaft, battery light—a car can have as many as 30 sensors operating to keep everything running properly and safely. Some of these sensors even activate life-saving features like airbag releases.

Steering Functionality


From adjusting the volume of a song, indicating a lane change, or placing a phone call—the steering wheel is a hub that communicates with the mechanical, electrical, and electronic parts throughout the vehicle.

Dashboard & Display

Speedometer, odometer, turn signal indicator, fuel gauge—a car uses these to communicate with the driver, keeping them informed while maintaining safety throughout the trip.

Communication & Entertainment

For many, a drive without a radio, or bluetooth connection is unimaginable. Back seat entertainment can also be a saving grace for families on a road trip. With opportunities for built-in wifi and satellite connectivity, cars are evolving to become more comfortable and dynamic every day—keeping you plugged in and charged even on the road.



Back-up cameras help facilitate easier parking jobs and feed into the driver’s display. Dashboard cameras activate in an instant to record a sudden accident. Whether it’s for personal security or driver support, the latest vehicles are now providing camera options consisting of a 360-degree birds-eye-view of their cars.

Driver Assistance Technology

Features such as auto-braking, motion control, and parking assistance have enhanced the driver’s experience and helped in maximizing safety. These technologies need to work intuitively and automatically, using robust and varying connectors to facilitate lasting connections.

Heating & Cooling Systems

From ventilation to seat comfortability, the HVAC systems within newer motor vehicles have become incredibly technical and intricate in design features. Overmolded wires and pins help to keep everything operational at the touch of a button.

On-Star & In-Vehicle Security


Roadside assistance, stolen vehicle alerts, and automatic crash support systems have now become one of the leading factors in decision-making when purchasing a vehicle. In those moments where the panic sets in, features like On-Star provide a level of protection that consumers find comfort in.
