Although my 7" light is from Custom Chrome i fitted bullet connectors to the light and stock wires and they sit inside the shell. Simple job anyone can do.

 

Pulled the stock wiring out of the stock headlight and inserted same into new 7" shell... simple.

 

How did the old wires come out? I thought they were attached to a plastic connector? Also, is there a ground on the stock unit? The aftermarket unit I bought has a ground wire soldered to the bucket itself. Any help would be appreciated before I begin taking my stock unit apart to put my 7" on.
