If all you are wanting to do is get power to the locks, hook it up to another car with jumper cables. If you have a slimjim, which I think you said you did, the access point is about 5" below the lick cylinder. Put the hook end of the slim jim down there and wiggle it around until you see the lock moving. When you do, pull it up. Mustangs are some of the easiest cars to break into I swear. If you cannot get the lock to move, try the passenger side.

 

How do I hook it up to another car with jumper cables??? I can't get the hood open?

We tried the clothes hanger loop idea. It did not work for us. We got the loop around the lever but couldn't pull it open. We literally pulled so hard it was bending the door lever but it wouldn't open because we were only pulling it up instead of out. Put some nice scratches around the window though (not recommended method).

Anyways, my buddy brought his universal slimjim set over, and then my neighbor saw what we were doing and used 2 screw drivers and a long knife and popped open the lock in 5 seconds. It was so simple that we were pissed that we didn't think about it. Now that I've seen that technique I think I can pretty much open any lock that is like my '95 Mustang's... We asked him where he learned that from and he said 10 years ago in college he worked one summer with a repo guy, and the rest is history.

Anyways, thanks for all the replies.
