headlight wiring

my teg has one pieces that what it came with when i bought it and i was wondering what i would have to do to put stock lights back in as far as wiring goes or do i have to do anything at all? any help would be appreciated

if you want help, we need more info. go and see how are the one-pieces wired up? is the stock usdm headlight harness plug still there or has it been cut? :think:

2 9004 sockets
2 stock usdm round fog socket
and the wireing diagram
