I have followed the instructions exactly as posted in this thread
I am using a 30amp relay. When I initially hooked everything up to the switch the lights came on and worked fine. After installing the switch where I wanted it and hooking everything back up, now the lights will not power up. I have power going to the relay with in inline 20amp fuse, and power coming from the relay into the cab to the switch. Every time I flip the switch the 20amp mini fuse in the fuse tap blows. What could be the problem?
