Review on 🔌 Pipeman's Installation Solution: 10 Amp Inline Power Noise Suppressor Filter (2-Pack) - Eliminator Isolator for Universal 12-Volt Car Audio Radio Ground Loop by Aaron Wood

Old car gets new rear view camera and touchscreen audio, I couldn't get rid of the generator noise. Delivery was slow but worked. It shows red blue and black wires. Connect the red and blue wires to my yellow ignition wire on the back of the car radio and the black to ground. If you connect them to the red wire with the constant power red wire, it won't work.
