Fuse Taps for Dash Cam Hardwiring

The add-a-fuse must match the vehicle's fuse format and be oriented correctly. Use a suitable circuit, separate protection for the accessory and a proper ground.

A fuse tap for dash cam installation adds a separately fused accessory branch at the vehicle fuse panel. The tap must match the exact blade size, preserve protection for the original circuit and be installed in the correct direction relative to the supply side.

Common questions

Questions before you buy

Which fuse tap do I need for a dash cam?

Match the physical fuse family used by the chosen panel position and the rating specified by the hardwire-kit maker. Similar-looking blade formats are not necessarily interchangeable.

Which fuse should I tap for parking mode?

Many kits need one switched and one constant circuit, but the correct choices depend on the vehicle. Verify them with proper documentation and testing, avoiding restraint, braking and other critical systems.

Does fuse tap direction matter?

Yes. Orientation determines whether the original and added circuits receive intended fuse protection. Identify the supply side with an appropriate meter and follow the tap maker's diagram.

What fuse rating should a dash cam use?

Use the value specified by the camera or hardwire-kit manufacturer for the accessory branch. Never increase the vehicle circuit's original fuse rating.

Can a fuse tap cause battery drain?

A constant circuit can keep parking mode active. Use a compatible low-voltage cutoff and correct settings, and investigate abnormal drain rather than fitting a larger fuse.
