I am connecting a headlight from one trim to another trim.
Trim A vehicle is going to have a Trim B headlight.
Vehicle A Outputs Are:
--AUTO Daytime--
DRL Function = Dimmed LED low beam projector.
7443 Running Light = OFF
194 Corner Lights = OFF
7443 Blinker blinks normally not affecting low beam DRL.
--AUTO Nighttime--
DRL = Off
LED Low Beam Projector = On
7443 Running Light = ON
194 Corner Lights = On
7443 Blinker blinks normally not affecting Running Light.
Trim B Headlight Needs:
--AUTO Daytime--
LED DRL ARRAY = ON (Full Power to LED Array on the headlight.)
LED Low Beam Projector = OFF
LED Corner Lights = OFF
LED White Running Lights = OFF
Blinker Turns off DRL during blinking on that lamp, then DRL turns back on after blinker stops blinking.
--AUTO Nighttime--
DRL LED Array = OFF
LED Low Beam Projector = ON
LED Corner Lights = ON
White LED Running Lights = ON
Blinker turns off white running lights during blinking on that lamp, then Running Lights turn back on after blinker stops blinking.
I have looked at the relays and I am stumped at what all I need here.
I have gathered so far:
If low=on + corner=on then low=on & drl=off.
If low=on + corner=off then low=off & drl=on.
Vehicle Trim A:
Headlight Switch (Auto) = Dimmed output of LED Lowbeam projector. All Other Lights are off.
Headlight Switch (Marker) = Dimmed output of LED Lowbeam projector, 194 Corner & 7443 Marker lights are on.
Headlight Switch (Lights) = Full output of LED Lowbeam projector, 194 Corner & 7443 Marker lights are on.
Headlight Switch (DRL Off) = Everything Off
{Signal On = 7443 Signal Flashes}
Vehicle Trim B:
Headlight Switch (Auto) = DRL LED Array Full Brightness. All Other Lights are off.
Headlight Switch (Marker) = LED Corner & White LED Running Lights are on. LED Low Beam Projector Off. DRL LED Array Off.
Headlight Switch (Lights) = DRL LED Array Off. LED Low Beam Projector, LED Corner & White LED Running Lights are on.
Headlight Switch (DRL Off) = Everything Off
{Signal On (During DRL=ON) = LED Signal Flashes. DRL LED Array Lights are off during signaling.}
{Signal On (During DRL=OFF) = LED Signal Flashes. White LED Running Lights are off during signaling.}
Trim B Headlight:
With (+) to white running light, it turns on.
With (+) to both white led running lights and (+) to the LED signal, both white running lights and signal are on.
BUT
Putting (+) to the DRL array and (+) to the LED signal, DRL Array turns off when signal turns on.
What relays, or series of other things would I need to put Trim B headlight on Trim A vehicle?
If there are any Relay gurus out there that sees a better way to accomplish the above, I am open to suggestions.
Thank you in advance.
