The tail fuse is located after the relay so the relay is likely not the problem. You likely have a shorted wire or something wrong with the dashboard illumination.

There is a knob for controlling the brightness of the dash. Try unplugging it, tried the fuse and see what happens. It'll help decide if the problem is with tail lights or the dash.

The dash is fully disassembled and disconnected. All the tail light bulbs have been removed too. The fuse continues to pop once the lights are switched to on. I have headlights, brake lights and blinkers.
Thank you.

 

I agree with sefiro, it sounds to me like there is a wire associated with this circuit, downstream of the switch, that is shorting out to ground. Let us know exactly which fuse is blowing. We can help you with the downstream wiring from that fuse to narrow the possibilities down.
