Turn the key off to do the electrical work in this part. 12 volts isn't enough to hurt you (you can't even feel it), but you could still short out something by mistake. Many recommend disconnecting the battery.
The tail lights and turn signals are located in a water resistant rubber boot at the rear of the electrical panel.
- Clip the ziptie closing the top of the boot.
- Roll back the sides to expose the wiring.
The turn signals use 3.5mm bullet connectors. These are the same size as the bullet connectors on the 4-wire turn signals, so they will plug right in and will be usable immediately.
However, the tail and brake lights use a unique 3-wire harness and connector. This will require some splicing to wire up, which I will cover in Part 2 next week.
