I added LED taillights to my car and now my Audiovox CCS-100 cruise control doesn't work anymore because it can't see the rear lights.

I added a 5 pin relay like this;

30 - Purple wire from CC
87a – Ground to battery (joined with 86)
87 - Constant 12v from battery
86 – Ground to battery (joined with 87a)
85- To brake pedal switch

...BUT as soon as I turned on the car all the wiring from the + and the ground melted and made tons of smoke... so something has to be wrong.

Does anyone know how its supposed to be wired? Before the LED's it worked fine, the purple wire from the cruise control was directly wired to the brake pedal switch and all worked.

HELP!
