how do i do it on a 04 silverado?

the directions at http://www.l13.us/smf/index.php?topic=2563.0 do not work because i dont have a purple plug like it says to use. i have a blue, white, and grey plug on my bcm

edit:

for 03+ cars on the BCM you are going to use two plugs. C3 and C4. C4 is blue and on the left. C3 is brown and in the middle. the right one is blue and that is C2 which is where you do the 4-high mod at.

on C4 the black wire is in B7. On C3 the white wire is on A4. i just put a wire tap on both wires and put a blade terminal on both ends of the resister. then just plug the resister into the two taps. remember to plug all the Cx plugs back in.

 

Do it at the sensor at the dash... there will be a black wire and a black/White Wire... Cut the Black/White wire and put the resistor there...

 

Nice mod for those with HID's

 

so i put the resister inline with the black wire that has a white stripe?
leave the all black wire alone

 

Right... If it doesnt work, switch the resistor to the other wire... Wont Hurt anything...

 

I don't think that will work unless you bypass the photodiode....you could jump across the 2 wires with a resistor, but if the resistor is only inline, as the ambient light gets dark, the photodiode's resistance will still riste towards infinity and turn the auto lights on. If you bypass the diode, the circuit will stay complete and current will flow through the path of least resistance, which will be the resistor as the sun goes down

 

ok can u explain your way then?

 

cant i just cut one of the wires going to the sensor and leave it not connected?

 

is it possible to cut it out and totally disregard the sensor. then the only way to turn the lights on is with the switch.

 

Can somebody do a full write-up with pics. I need to do this.
