The bem is locationed next to your steering wheel on the left.
I attached a pic with an arrow pointing to where it is exactly..
(Sorry xyphoid only pic i had with dash apart was ur car on hand lol!)
I suggest not doing the alarm yourself unless you actually know what your doing so you wont get yourself into sheet! :s2:
go to
www.fordmods.com and there will be info on the cables etc there for you if you do decide to give it a go!
