Both Blinkers blink when i turn on a turn signal

Right - since diodes are basically electrical one-way valves & LED's are Light Emitting Diodes.

The branches headed to the right are to the dash indicator(s), I expect - so if there's a back-feed voltage induced in the opposite circuit, it would be in the right 'direction'. iirc, typical gate voltage for led's is about 3.5, so it wouldn't take much.

That's where I think that adding another power diode, in the "correct direction", would do the trick. It should drop the voltage across the indicator LEDs to below threshold. It's either that, or start monkeying around with a Zener circuit to act as a switch.
