Using bottom side markers as turn signals. Is it possible?

[Maverick2023]

I’m looking to replace the whole harness and tap into the turn signal module and the DRL. Wiring . At the moment I can’t find a connector that would exact match to oem connector that has all the wires necessary to do so. Anyone has any input?

You want the bottom side marker to stay on but blink when turn signals are activated?

For that a simple relay on each side should do the trick. Run the marker light power through the NC (normally connected) side of the switch element, trigger off front turn signals. That'd make them turn off when the front flashes and back on again. Might need to add a resistor or disable bulb outage detection if the BCM doesn't like the resistance.

Edit: If you want it to flash brighter that's a bit trickier since there isn't really a dual filament 194. One possible avenue is supposedly there are some that make a switchback LED 194 where it changes color by switching the input polarity.

This might be possible with Forscan. But im no expert with it maybe someone else can chime in or go ask in the Forscan section.

Did you ever get the side markers acting as a turn signal? I've seen where the higher side markers had a rehad to make them work but I like them to be lower and not so high.
