Instrument Panel LED Conversion and Polarity for the instrument panel that looks like this:
I couldn't find anything for the polarity of the instrument panel circuit board so by trial and error here it is. Note: LEDs unlike regular bulbs must be oriented properly by polarity.
Instrument panel lights from right to left (as seen from the circuit board)
1) up -
2) up +
3) up -
4) up -
Right Turn Signal) up +
C Diff Lock) up +
Bright Indicator) up -
Left Turn Signal) up +
Cruise) up -
AT Oil Temp) up -
ABS) up +
Low Fuel) up +
Battery) up -
Brake) up -
Air Bag) up -
Seatbelt) up -
Door Ajar) up -
Low Oil) up +
Check Engine) up -
Some notes:
Tried blue for the panel lights but they washed out the gauge needles making them hard to see, tried red and it works and looks great.
Red didn't work so well in the AC controls, tried blue (see night photo) but it isn't quite right either so I'll probably go back to white.
You can put any color you want in the indicator/warning lamps and the LEDs will make it that color even if a color filter is there. Exception of course a white LED behind a color filter would be the color of the filter.
Blue turn signal indicators look great.
I have a 5 speed so I didn't put an LED in the AT Oil temp position, left a bulb there.
