I've installed the McCulloch HID's and when I go to re-attach the negative battery terminal I get a spark. Everything is an easy plug and play except for the black wire spade and white spade terminal. I assumed the black is negative and plugs into the terminal that has the 2 wires meeting as one. What am I doing wrong?

 

I got McCulloch HID 6,000k with bulbs but the bulb won't fit. What do i need to do? Email is: fifa_sherif@hotmail.com

 

~ make sure you have an H7 bulb.
