They should have the instruction come with the box. I used the MMP wiring kit on 2 of my friend's cars, the instruction is clear and easy to follow.
For the MMP wiring kit, the longest one goes through the firewall into the headlight switch/euroswitch. Then, 2 long wires with plastic grommet go into headlight wiring connector plug pin#2 (if I remember correctly) at the back of each headlight housing. Last, the 2 shortest one go to +ve and -ve terminals of the battery. Remember to put the inline fuse into the fuse holder otherwise the foglight will not turn on.
