No problem here are the instructions: dome panel shown is the previous model which came with the LED kit. The new panels are much more powerful!
1. Pry off map light lens cover using a small screwdriver
2. Remove oem bulbs the map light housing
3. Select the connector from the bag of connectors which resembles the oem bulb base.
*some 4runners use the ba9s and some 4runners use the festoon bulb. Festoon looks like a slinkie.
4. Test the map lights by putting the switch in the on position. If it does not work, try flipping the adapter or try pulling out the bulb adapter and mount it the opposite way!
5. Remove 3m adhesive backing and mount the light in the manner in which you decide to mount it
6. Cover the light housing with the oem lens
7. repeat steps 1-6 for the dome lights in the second row and cargo area
8. Enjoy your LED kit and make sure you post pictures on the forums of the kit in action(this step is optional)
