Step 3: Install New LED Reflectors

  • The new reflectors are marked (L) and (R) to indicate the side it goes to.
  • Disconnect the harness and feed the male end into the hole in the bumper.
  • Once the harness is fed through the bumper, secure the new reflector in place, reusing the factory 10mm nut.
  • Do the same for the other side.
  • Once the reflectors are installed, move to the rear fender liner and remove the (2) bolts and push pin, holding the liner to the car.
  • Pull back the liner and disconnect the rear side marker.
  • Now take the previously disconnected connector harness and plug it into the new rear reflector.
  • Then connect the factory rear side marker light to the Form lighting harness.
  • Reconnect the Form lightning harness to the rear OEM side marker.
  • Take this time to zip tie the wiring up and out of the way.
  • Reinstall the fender liner.
  • Repeat these steps for the other side. After this you are good to go!
