Not actually from the ECU, to the ECU.
You need to cut the turn signal wires from the lamps control unit. Light blue and Light blue-black. So these wires should not go into the unit anymore.
Then you run the wires all the way back to the lamps. So now it is directly from the Turn signal stalk through the cluster/relays and fuse box directly to the lamps (same as euro versions)
So now you need 2 per side resistors (20W 8Ω) to fool the ECU into thinking it has 2 bulbs back there still.
Use a common ground for both.
Then one goes to stop lamps (light blue-yellow/light blue -red) and one for parking lamps (yellow/black for left) (yellow for right).
So lets see if I can remember how it works:
-------turn signal lead(turn)----->resistor and to lamp harness--->ground
-------Light blue-yellow(stop)-------->resistor and to lamp harness--->ground
-------Yellow(parking)------->directly to harness
-------Black (ground)--------->directly to harness
On the two bulb harness you need a 7528 bulb( dual filament)
For turn a 7506 Bulb (single filament) Preferably ORANGE in color to be correct.
Top of harness:
- pin 1: grnd
- pin 2: stop (make sure first it could be parking)
- pin 3 turn
- pin 4 parking
Hope that helps, call if you need help.
