The Model S Lighted T was developed over a period of about 6 months by Rick Hesel, a Model S P85  owner who began developing modifications for his car before it was even delivered (in May 2013). Over a period of several months a number of betas were developed and tested by a group of six Model S owners.  The production version, manufactured in Hong Kong, was developed in collaboration with Oznium Inc, an online retailer specializing in LED accessories.

Rick is developing several other accessories, including a lighted T for the deck lid and a front-rear camera switch, which deploys a Tesla rear camera on the front of the car and enables switching from rear to front views on the touch screen.   These accessories will be made available in April 2014.

Installation Steps


Remove Model S Nose Cone

The first step of the process is to remove the Model S nose cone.

Remove Factory Tesla T and Arch

Slide dental floss behind the emblems and use a back and forth sawing motion until the emblems are fully detached. Use adhesive remover to remove all glue residue from the back of the factory Tesla T and arch.

Tesla Lighted T Power On/Off Options

Powering on and off the Tesla Lighted T can be achieved through three types of options – on/off with the headlights, with the daytime running lights (DRL) or through a custom dimmer option.

 


Power On/Off with the Headlights

Tesla-Model-S-Lighted-T

In the exposed area under the liner locate the wire connector plugged in to the back of the headlamp assembly. Locate the red wire with a white stripe. It’s the first wire closest to the nosecone in the lower row. That wire provides 12v power to the headlamps and will be tapped to provide 12v power to the lighted T and arch. Gently pull that wire apart from the surrounding wires.

Tesla Model S Lighted T Headlight Plug

Take a Posi-tap connector of appropriate size. Following the instructions for the Posi-tap (see video: http://www.youtube.com/watch?v=Yiimgl-Rdmw) screw on the tap side to the red wire with white stripe. Attach a 3 foot piece of the red hook-up wire to the connection end of the Posi-tap then screw it back on to the Posi-tap assembly.

Tesla-Model-S-Lighted-T-Headlight-Plug-Positap

Next run attach a female spade connector to end of the red lead from the Posi-tap. This will connect to the male connector on the lighted T and arch.

To complete the power and ground connection, crimp a female spade connector on the end of a 2’ long piece of black hook up wire and then crimp a fork spade connector large enough to fit on 10mm bolt on the other end.

Loosen one of the several 10mm bolts connected to the aluminum frame under the frunk plastic piece you removed and attach the U spade connector and tighten down the bolt. This grounds the circuit

Tesla Model S Lighted T Ground Connection

Place the nose cone near the front of the car just under the crash bar and carefully connect the red female spade connector from the headlight connection to the red male connector on the lighted T and arch. Do the same with the black connection from the ground.

Before snapping the nose cone back into place, turn on the headlights. The Lighted T should light. If not test all of your connections to make sure they are correct and secure.


With testing complete, snap the nosecone back into place on the front of the car, taking care to thread the leads from the T in front of the chrome piece to which the top clip of the nose cone attaches, taking care not to crimp or otherwise stress any of the connections.


Power On/Off with the Daytime Running Lights

Follow the same instructions as powering the lighted T from the headlights, but with one exception – attach the Posi-tap to the orange wire with black stripe in the headlamp wire plug bundle. All other steps are the same as the on/off with headlights procedure.


Power on and off with special effects (dimming, strobe, and heartbeat) using the Oznium controller

  1. Crimp a male spade connector on the ends of the red (12v input) and black (ground) leads on the Oznium receiver box.
  2. Crimp a female spade connector on the ends of the yellow (12v output) and white (ground) leads of the Oznium receiver box. Only one set pair of the yellow and white wires is needed.  The other pair can be clipped off or ignored.Tesla-Model-S-Lighted-T-Oznium-Controller
  3. Using double faced tape or Velcro, attached the Oznium receiver box to the top of the crash bar about a foot left of center.Tesla-Model-S-Lighted-T-Oznium-Mount
  4. Locate the Add-A-Fuse. Crimp a male spade connector to the red lead. The take 4 foot piece of red hook-up wire and crimp a female spade connector on one end and connect it to the Add-A-Fuse male spade connector.
  5. Place the 5-amp fuse into one of the Tap-A-Fuse slots. Then pry off the cover to Fuse Box #2, locate and remove fuse F47 (the glove box light fuse), insert that fuse into the second Add-A-Fuse slot, then insert the Add-A-Fuse into the empty fuse slot.Tesla-Model-S-Lighted-T-Tap-Fuse-Box
  6. File a small notch into the Fuse box cover so it will clear the protruding Add-A-Fuse red lead. Replace the fuse box cover with the red lead loosely placed in the frunk opening.
  7. In the space under the frunk liner, run the red lead from the Tap-A-Fuse to the top of the metal crash bar behind the nose cone and cut it for the proper length to attach to the red lead of the Oznium receiver box.
  8. Crimp a female spade connector on the cut end of this lead.
  9. Crimp a female spade connector on the end of a 2’ long piece of black hook up wire.
  10. Crimp a fork spade connector large enough to fit on 10mm bolt on the other end.Tesla-Model-S-Lighted-T-Fork-Spade
  11. Loosen one of the several 10mm bolts connected to the aluminum frame under the frunk plastic piece you removed and attach the fork spade connector and tighten down the bolt.  This grounds the circuit.Tesla Model S Lighted T Ground Connection
  12. Connect the red wire female spade connector from the Tap-A-Fuse and the black ground wire female spade connectors to the red and black male spade connectors on the Oznium receiver box.
  13. Place the nose cone near the front of the car just under the crash bar and connect the female spade connector on the yellow lead from the Oznium receiver box to the male spade connector on the red lead from the lighted T.
  14. Do the same with the female spade connector from the white lead on the Oznium receiver box and the black wire male spade connector from the T and arch.
  15. Now take the Oznium controller and press button #1. The T and arch should light up.  Successive presses on button #1 should dim the T and arch. Similarly, test buttons #2 (strobe) and #3 (heartbeat) to be sure they are working properly.
  16. Turn off the T and arch by pressing button#4.
  17. With testing complete, snap the nosecone into place on the front of the car, taking care to thread the leads from the T in front of the chrome piece to which the top clip of the nose cone attaches, taking care not to crimp or otherwise stress any of the connections.
  18. If you car has the Tech Package with Homelink you can sync operation of the Oznium remote with Homelink. Do so following the syncing instructions for Homelink on the touchscreen. You’ll need to sync the on function with button #1 on the Oznium remote and the off function with button #4.

Optional dashboard LED monitor of Oznium 12v dimmer This provides a simple way to monitor the status of the lighted T if it’s controlled by the Oznium 12v dimmer and strobe switch. An LED is wired in parallel with the output of the Ozium controller, a resistor is added to the circuit, and the LED is placed in an inconspicuous place on the dash, as shown in the photo below. Here’s how:

  • Cut a about a 6 foot length of the black and red hook up wire (long enough to reach from the Oznium controller output connections (yellow and white), under the diver’s side frunk cover, through the door jam, and into the left side of the dash. Strip off about ¾ insulation from each wire on one side.
  • Before crimping spade connectors to the Oznium yellow and white wires (step B.1.b above), twist together the ends of the yellow and red wires, then the white and black wires. Then crimp a female spade connector on each. Make the connection to the lighted T as above, and route the red and black hook up wires along the fender channel. Then run the wire through the narrow opening where the fender meets the door jam. Pull the wire through into the door area.
  • Next pull the rubber seal away from the door jam and run the wire under it.
  • Using your pry tool, remove the small flap on the side of the dash. Solder a 1/8 watt 400ohm resistor to the red wire then solder the other end to the anode side (long lead) of the LED. Then solder the black wire to the cathode lead (short) of the LED. Insulate all of the wires. Bend the leads of the LED at about a 45 degree angle as close as possible to the LED head, then gently slip the LED into the gap between the vinyl cushion and the fascia of the dash. Stuff all of the excess wire into the side opening then snap the cover back on. The LED will mimic the operation of the lighted T.Tesla-Model-S-Lighted-T-LED
