I did do a search of the forum, but am still unable to find out what color wires are required for the LED turn signals in the front and rear. I know one end of the load equalizer goes to brown for ground, and i hear that yellow is for the brake lights. is that correct? also what color are the wires for the front and rear turn signals. especially on the headlight housing it seems there are two sets of plugs going into it. i may be wrong it was kinda hard to see in the garage. any help would be much appreciated.

Yor resistor will need to be installed in series with the LED light instead of in parallel.

oh ok. one end goes on the positve lead to the bulb the other to ground right? do you know the color of the wires?

amdeutsch

Nope. Thats parallel.

how do they go then?

positive original wire gets cut and goes to one side of the equalizer, the other wire out of the equalizer goes back to the other cut wire. SERIES circuit

Wrong. The resistor needs to be connected parallel to the LED bulb. The whole point of needing an equalizer is to fool the car's computer, as a LED bulb draws much lower current than the computer considers normal. If you connect the resistor in series, the current will be even less than in case of LED bulb only, so this is not going to help achieve the desired result.

if the led bulb draws less current than the stock bulb, and the voltage remains constant, the led bulb would have to have a higher resistance... but, if the led bulb actually has a lower resistance than the stock bulb, that would mean the led bulb actually draws more current.

v = ir

if the led bulb draws less current than the stock bulb, the resistor would have to be connected in parallel to decrease the total resistance and maintain the same voltage. if the led bulb has a lower resistance than the stock bulb, then it would have to be in series.

Most LEDs require a current limiting resistor unless it is built into the design. Plus there are also safety and failure conditions to consider. A LED is a diode; what happens if it fails open or short?

1) Resistor in series
a) LED fails short -> all current will be used up by the resistor
b) LED fails open -> no current draw

2) Resistor in parallel
a) LED fails short -> direct short to ground
b) LED fails open -> all current will be used up by the resistor

does anyone know the color of the wires for the front and rear turn signals and brakes?

You can always find the wire by using a multimeter. Connect one of the probes (negative or ground) to any grounded point on the car, then use a thin sewing needle paired with an alligator clip as the second probe. Use the needle to puncture the insulation to get through to the wire - this is not going to damage it if done carefully. Turn signal is easy - just turn on the emergency blinker and find the wire that has voltage pulses. For the brake signal, you will need someone to sit and press the pedal as you observe. Good luck!

i was just out in my car looking at the wiring harness and thinking the same exact thing. that's what i'll probably end up doing.

Mine are wired in Parallel. In the front turns, its a load equalizer, and on the city lights, its just a nother 4w bulb and socket scotch locked on.

Don't worry, the MB computer will cut the power entirely if you don't have enough draw.
