I'm pretty sure that disabling your turn signals is illegal, even in Puerto Rico. I've done that the exact thing on my 4runner when I replaced the front bumper. You need a total of four relays, two for each side, and wire them up...... but you need a diagram. I'll see if I can find you one.
May I ask as to the point of this? You already have two amber parking lights on the front of your car.
