Per 81Runner
The console and climate control lights are 5630 style, t4 for the display, t3 for everything else.

buttons as well. Those are 5628 t3. Multiple colors, no issue with voltage,


This shows 8 bulbs total.

These are the bulbs.


C = 09017 = T4= NEO4 led Main screen/clock 2 qty (These are the only two with the 6 volt/12 volt concern)
D= 09018 = T3 = NEO3 Reset and Mode 1 qty
A= 09015 = T3 = NEO3 Three control buttons 3 qty
E = 09019= T3 = NEO3 defrost/recirc 2 qty


12Volt mod info:
Concern with only 6 volts going to the main sceen/clock bulbs. Most LEDs need more. 81Runner seems to be working. Read about using non SMD bulbs or doing a "12 volt mod".

Separate the positives on the LEDs. Solder wire to them. Run to a 12 volt source. I chose my accessory wire on my head unit wiring harness. I used a male/female connector so I could remove it easier.

The wire is on the top row, second wire from the passenger side with the white connector oriented the way it is when it is connected to the HVAC. I have a 04 sport and the inner contacts were also the positive side of the board. I just soldered wires to the positive lead on the LEDs, and then taped up the exposed area. I then used a posi-tap to tap into the 12V wire. I feel this is better than using a regular inline tap or soldering since they just screw together and can be unscrewed and screwed back together as many times as you like



LED vs SMD: What's the difference? LED stands for Light Emitting Diode. ... SMD stands for Surface-Mount Device.

Up next: figure out differences between 5630 and 5628.
