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.
Your Cruiser Control is probably grounded to your brake light. Why dont you just splice in the LED light into the existing wires instead of onto a relay? Good Luck.

Most Cruise control systems will turn off if your brake lights are out so you will know to check them.
Why did you use a relay for your lights and cruise control?
Did you have it hooked up this way before the change to LEDs and did it work?
To me it looks like when you press the brake the cruise control gets connected to the 12v so if you need it to have that 12v to be on then you have 87 and 87a reversed. If to function it needs to see ground and should not receive voltage from that side you may have killed your relay or cruse control.
Help with Cruise Control and LED taillights!
I move at the speed of awesome.
