I got one wired the other day, mine came with instructions, it depends if its a ignition button or a power button, if its just ignition the black wire goes to the ground and there are two terminal cables and one positive that get wired into the terminal 15 and ... erm (50 i think) in the back of the key chamber, make sure you do a tight job if they go loose it wont start - acting like its a flat battery, tbh you can get it done professionally from £20 at a garage.
