I'm looking for a schematic for the keyless entry system for a 99 to 04 SD so that I can add on to my truck. I'm trying to find one in a wrecking yard and need to know where to look for the required parts and the associated wiring.

If you already have power locks, an easier task would be to install a remote start unit. Most of them have keyless entry, and if you get one with a superheterodyne antenna, the range is many times that of a stock system.
Plus, you get the convenience of remote starting your truck when it's colds outside. Most of them also have a built in turbo cool down timer feature.
The thing I enjoy the most is the power window roll up module. I can hit a bitton on my key fob and it rolls up the windows for me. It's great when it starts raining and I just need to push a button instead of running down stairs or to the other end of a parking lot.

The only thing I liked better about the stock system on my truck is that the key fobs are sturdier. That being said, I still prefer the remote start over the factory system, and I will be installing one on every vehicle I own for the rest of my life.

If you just want keyless entry you can get a ford unit from http://www.troyfordaccessories.com/ You only have to wire up two relays and connect into 6 or 7 wires on the truck.

 

What I really want is the keypad on the door. That way I don't have to worry about locking my keys inside. I figured that it would be easier to get one from a junk yard.
