Buying Guide

Confirm connector type

Match OBDII, 10-pin, RJ11 or barrel connectors to your vehicle and detector to avoid returns or modification

Prioritize mounting location

Choose mirror-mount or dash/tripod mounts based on sightlines, windshield curvature, and ease of access to controls

Check direct-wire vs OBDII

Direct-wire kits integrate with vehicle wiring for permanent installs while OBDII cords allow plug-and-play power without splicing

Look for brand compatibility

Accessory wiring and bracket patterns often match specific detector brands like Escort, Cobra, Uniden or Valentine for a secure fit

Evaluate cable length and routing

Longer cords and included mirror wires simplify clean routing but verify they reach your desired mounting point
