Im finally about to try and convert my steering wheel controls to leds and had a question about resistors. I used a led calculator and its says i need 150 ohm 1 watt resistors but the 1 watt resistors are rather bulky and seem like overkill plus they only have the 1/2 watt resistors available at the local radio shack. So anyone that has done this did you use 1 watt resistors?

You can use 1/4 watt resistors for that application.

The problem with the controls is if you wire them in parallel like they are from the factory then the wattage needed increases. For me I added an additional led to each switch so each button had one so your talking about 2 groups of 3 leds in parallel. I ran 2 1/2watt in series on the feed wire to the switches behind the airbag.

Cool that was my plan...im copying exactly what you did. Do you happen to remember which wire is the positive feed to the switches by chance?

I'll post these here too so if anyone else wants to try this. Blue is positive and red is negative. The third led was added to illuminate the buttons equally. In order to do this there is a piece of plastic under the button that needs to be removed. I tried it with just the two and they didn't light the top bottom very much.

Thanks again for the pics they were very helpful. I was able to finish one side already but lost one of the leds for the other side so i gotta wait for another to get here before i can finish the other side.

Looks good. Get the resistors in the harness too?

Yup..went with two 67 ohm 1/2 watt resistors on each side. The leds i went with are darker then the dash lights but match my radio and hu mount so it will look good. Once again thanks for the help

Forgot to post pics when i was done, i went ahead and got an extra set of controls and used the blue covers from the stock bulbs with white leds
