Let’s see how to pass a cable from the engine bay to the cabin on a Renault Trafic III: in the engine bay, locate a black rubber grommet on the passenger side; using a flat screwdriver, make a small hole in the bottom of the grommet. Look for an area without existing wires.

Use a thin cable to pass it into the cabin: it will exit in the glove compartment, which you will need to lower (this is normally done to access the fuse box). You will see the end of the cable you passed from the engine bay. Gently pull it towards you, and from the engine side, seal it with sealing tape or silicone sealant.

Add the cable to the fuse box with a piggyback connector to safely draw power.

How to Remove the Rear Seat of a Hyundai Tucson?

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space. Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins. Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat. Be careful of any electrical cables or components that may be connected to the seat during removal. Once the rear seat is removed, the disassembly is complete.
