The ground circuit for your Honda Civic brake lights can be found on the rear frame rail. The ground circuit will be on the drivers side frame rail.
Bolt it to the frame.
It's attached to the ground.
the frame!!!
It's attached to the ground.
There are 3 different grounds. Engine to body ground. Engine to frame ground. Engine to battery ground.
The frame is the best ground source on nearly all vehicles (assuming it uses a negative ground system, which is the most common type-negative post of battery is attached to the frame). If the frame can't be used, a metal part attached to the frame *may* be substituted, but always make sure to clean the attachment point to BARE metal, as paint or powder coating can act as an insulator, preventing a good ground connection.
An A-Frame
From the battery to frame directly under the battery box. From the frame to the engine at the motor mounts with a short ground cable. Usually on the drivers side.
The frame of reference for a plane moving at 500 km/h could be relative to the ground or the air. The ground frame of reference would consider the plane's speed relative to the Earth's surface. The air frame of reference would consider the plane's speed relative to the surrounding air.
Ground it to the vehicle frame or engine.
you can ground it right to the frame. just find a bare spot and put a screw with the ground wire
