Wiring: splice wires correctly, matching colours to functions

When wiring your tail lights, it is important to splice the wires correctly and match the colours to their corresponding functions. This will ensure that your tail lights function properly and that you stay safe on the road.

Firstly, you need to identify the wires in your vehicle that correspond to the brake lights, turn signals, and running lights. The colours of these wires will vary depending on your vehicle model. For example, in a Yaris, the purple wire is for the brake light, the teal wire is for the left turn signal, the yellow wire is for the right turn signal, and the green wire is for the running lights. You can use your vehicle's documentation or a multimeter to identify the correct wires.

Once you have identified the correct wires, you can begin splicing them. Start by snipping the wire and stripping both ends, as well as the corresponding wire on the unit. Twist the wires together and slip tight-fitting shrink tubes onto the ends. Then, twist all three wires together and bend one back so it forms a line. Push the shrink tube into place and heat it to secure the connection. Repeat this process for all the necessary wires, except for the ground wire, which should be attached to the grounding screw.

If your vehicle has a 7-pin connection, it is important to note that the blue brake wire is not always used. If your slide-in truck camper does not have electric brakes, this wire will not be connected.

Finally, test your tail lights to ensure that all the functions are working correctly. This includes checking the left and right turn signals, brakes, and running lights. If any of the functions are not working properly, double-check that the connectors are secure and there are no loose connections.
