Use a quick-connect to splice onto the brake light. The brake light is the large 3-wire harness inside the big rubber boot. The quick-connect punches a pin through both wires and creates a secure splice.
Don't worry about the ground wire. The 4-wire turn signal uses its own ground wire and we hooked it up in Part 1.
- Disconnect the brake connector by using a small screwdriver to release the locking pin.
- Using a small sharp knife, carefully cut open the plastic sheath. We just want to get inside the sheath. DO NOT cut any wires.
- Identify the green wire with a yellow stripe. This is the brake light power.
- Slide a blue quick-connect over the green wire with yellow stripe.
- Slide the closed end of your prepped blue wire into the other side.
- Make sure both wires are fully inserted. Then fold the cover over the top.
- Use a pair of pliers to snap it closed. It may take a lot of effort.
