Fog Lamp circuit breaker pops. Why?, Haven't a clue where to start Options

[Rav914]

Short background: I installed a set of Hella 500's on a car that didn't have fogs to begin with. I decided to follow the directions that came with the lamps. It didn't work. I just burnt up a wire (now repaired) and wasted my time.

So...I bought an OE switch and connected the lights to the wires already in the car.

Connections:
Black wire on lamps to the yellow and white wires from the car.
Blue wires on lamp (ground) to brown ground.

K on switch to gray/red.
31 on switch to brown ground.
15 on switch to brown/blue

on the CB panel I see the red/black, gray/red, white/blue, and white/yellow wires taped together and go under a black relay.

I'm assuming all is good. But when I turn on the lights and pull the fog light switch, the lights dim momentarily and then "snap", the CB pops.

What am I missing? Do I need to install the relay that came with the lights? I'm so bad with electronics, I don't even know where to start. Except that I checked and cleaned all grounds. I checked and traced all wires - no issues. (IMG:style_emoticons/default/sad.gif)

OK, I think I understand what you guys are saying....

I need to run a new 10 or 12 guage wire (the Hella supplied wires are 16 guage so I think I'm safe with the 914's 12 ga. wires) from the battery to the 30 terminal on the new relay. Yes?

The 85 terminal on the relay is connected to the K terminal on the switch. I can use a new wire or the one on the harness.

The switch is grounded on 31 and the 15 terminal with the brown/blue wire I leave alone.

Then I re-route the 87 terminal (white/yellow) and the 86 terminal (white/blue) to the new relay.

Correct?

Oh and yes great driving up here. My commute to work is down the west side of the island through all the twisties. Eight miles, two stop signs and one light. (IMG:style_emoticons/default/biggrin.gif)
