Hide 2 cables from the lights on the left side of the car (looking from the front) up the left side by laying them in between the white studs and then reconnecting the grey triangular plates over the top of them. To ensure a trouble-free installation of your light kit, please read and follow each step carefully. Before we hide the 2 cables from the right we will first install an LED to the blue light at the right side window. To do this, remove this section at the grey stud with clip. We will be installing lights to the headlights first. To do this, remove the following pieces from the front of the car. It’s time to neaten up all the cabling from the LEDs we have installed so far. Take the 5 cables from the front lights and twist/wind them around each other starting from the base working your way up. They should all come together neatly.

We will now install flasing LEDs to the blue spot lights at the front. Remove the grey plates with clips from the pole and then disconnect the round blue pieces from them. KIT itself : really nice KIT. You just simply can not compare to "without light" KIT. That is an another level.Before reconnecting the white Lego pieces which make up the front bonnet, ensure that the cables from the LEDs are laid in between the studs of the Lego plates underneath as per below example images.

Take extra care when inserting connectors to ports of Expansion Boards. Connectors can be inserted only one way. With the expansion board facing up, look for the soldered “=” symbol on the left side of the port. The connector side with the wires exposed should be facing toward the soldered “=” symbol as you insert into the port. If a plug won’t fit easily into a port connector, do not force it.

Before dive into the KIT itself I have to remark, that the customer service was just fantastic before buying the KIT. I had some doubts and questions but they were just provided one of the best support online.
