Easy Corner delete for M3!!!

basically what we are doing
is getting the wire that goes to the bulb
and putting a relay in the middle
so when the turn signals are getting 2.5v, when they are turned on with DRL, the bulb is disconnected (i.e relay off, bulb not lit)
but when you use your turn signals, the 12v goes to the bulb (i.e relay on, bulb flashing orange)
Ok here goes!

Parts list (radio shack)
1) 2x item 275-248 (12VDC/125VAC 10A SPDT Mini Relay)
http://www.radioshack.com/product/in...ductId=2062482

2) 2x item 276-1144 (3-Amp Barrel Diodes)
http://www.radioshack.com/product/in...ductId=2062579

3) 1x Item 271-153 (2 pack of 1W 1K ohm Resistors)
http://www.radioshack.com/product/in...ductId=2062296

4) 4x 5.6 ohm 25W resistors
i got mine from ebay from this seller
http://cgi.ebay.com/5-6-ohm-25W-Powe...3286.m20.l1116

first step is to extract the wire going to the turn signal from inside the headlight (white wire on both sides headlights)
that goes to the red/yellow points in the diagram
the wire you just extracted goes to the white point in diagram

now follow this wiring guide

the 2 resistors are wired in parallel (meaning just twist the 2 wires from one side of each, then do the same for the other side)

1 diode and 1 resistor are wired in series.
with the diode, the striped line should be connected to the red point, then the 1K ohm resisor is connected to the black point.
so it goes like this
red point---[|diode]--[resistor]--black point
that is to protect the cars circuitry from voltage that is released by the coil when it de-energizes (don't ask me what that means, i am just saying what i read )


the yellow and red points are connected
because in this case, we are using the power coming from the car to both power on the relay, and to give power to the bulb

in the case of having your lights on
there is 2.5V coming to the red and yellow points
that's not enough to energize the relay
so the 2.5v goes to the blue point which is sent to the 2 5.6 ohm 25w resistors
(so the car senses the correct resistance and no bulb warning)
now when you use the turn signal
the red/yellow get 14V, that energizes the relay and the 12v goes to the white point which leads to the bulb

as for the orange LED
it gets it power from a seperate wire (black with blue stripe on the passenger side, and black with green line on driver side)
now those colours are from the headlight plug that goes into the headlight
inside the headlight the LED has a black wire, and the turn signal has a white wire for both sides)
the ghetto way to get rid of the LED is to cut that black wire from inside the headlight= no LED

what i am going to do is to connect the LED with the turn signal
so it only flashes with the turn signal
