I did this. I bridged my blinker to my brake light. Pin 3 to 4.
But I had to add a diode on the blinker wire so my brake light current doesn't travel back up to the dash cuz my dash signals would blink when I braked.
the diode prevents current going back to the dash. But let's current come from the relay/dash. Put one behind the bridge on both bulbs. So current can only go one way, from either source of power. (Signal relay or brake relay)
green wire is the bridge. Sharing source voltage in this case the relays. But the diode limit current from going back up. Only to the bulbs. And cuts off there
