Whats Needed

1. 1999-2001 Cobra Amber Turn Signal Tail Lamps
2. Flasher part number from Ford is #5L5Z-13350-AA or EP-27 from Napa to save a bit
3. 16 Gauge wire
4. Quick Connects
5. Butt Connectors
6. Socket set and Ratchet (deep sockets)
7. Wire Stripper
8. Wire Crimper
9. Dykes

Step 1

Start by removing the factory lamps. This is pretty much straight forward. Remove the interior truck panels and unbolt the tail light. I recommend using a towel to slide under the tail light so it does not scratch the paint on removal. After they are removed Cut the connector off the harness and leave yourself enough wire to work with. Cut the connector off the new harness and splice/connect the old connector with the new harness. I chose to solder and heat shrink my connections, but you can do as you like.

You will have one green wire left over on the new harness. Attach a few feet of 16 gauge wire to it.

Step 2

After performing step one on both lamps and harnesses, make a jumper wire to connect your lamps to the third brake lamp. You could go right to the wire, but I chose this route because I did not want the wires to keep me from removing the lamps.

Step 3

Run the jumper from a green wire in the trunk. It is located near the FPDM. Inside the RR panel.

Step 4

Install the lamps and run your lengths of wire accordingly. Make the connection and secure all new wiring.

Step 5

This step is done under the driver’s side dash. First, remove your original flasher. It is located above the OBDII connector and should be yellow. The updated one is blue and will replace yours. Just plug it in and secure it as it was. Second, find the gray connector up by the steering column at cut the solid green wire for the brake interrupt. I chose to disconnect the harness, remove the wire from it’s terminal, insulate it and tape it up and out of the way.

And that’s it! OE with a touch of class!
