Many people have asked for a comprehensive article explaining how to remove the permanent EPROM from their Chrysler ECM's and replace it with a socket, so that it can be reprogrammed easily. Let's start with a list of the tools needed:

All pictures in this article are clickable for a larger version if you need to see something closer.
From left to right: Desoldering iron, sponge, T15 torx screwdriver, flush cut dikes, metal jar lid, toothbrush, solder, pocket knife. Not shown is a regular soldering iron, which will also be needed.
Desoldering iron: This iron is readily available at radio shack. I'll cover how it works later in the article.
Sponge: You use this when "tinning" the tip of the desoldering and soldering irons.
T15 Torx screwdriver: The screws that hold the SMEC/SBEC case together are T15's, you'll need this to get inside the SMEC/SBEC.
Flush Cut Dikes: Also available at Radio Shack, these are used to remove the eprom.
Metal Jar Lid: Something to squirt the solder from the desoldering iron into.

Toothbrush: Note the picture above, You'll want to use a pocket knife, or grinder to sharpen the end of the toothbrush. This is a VERY important tool in this procedure.
Solder: When you put the new socket in, you can't reuse the old solder, and you want fresh solder to tin the irons with anyways. Use rosin core solder.
Pocket knife: a utility knife would work even better, but either will do.
Regular soldering iron: Can't put the new socket in with the desoldering iron, it's too big. Radio shack has standard soldering irons as well. Keep the wattage down, I've used a 15watt iron on many projects, nice and safe. Try to get a "pencil" tip iron.

That covers all the tools you'll need. For a workspace, I recommend a WELL LIGHTED area, I use the kitchen counter with a huge fluorescent light fixture hanging under the cupboards. It works so well I didn't use a flash to take any of these pictures. This is important, the better you can see what your working on, the more likely your going to succeed without damaging the circuit board.
