First, you’ll need a 60/40 rosin core solder. It must be rosin core, not acid core, since acid core solder can damage the circuit board itself. You’ll also need DeoxIT, or a similar non-corrosive contact cleaner. Remove the two small screws in your PCM cover, and carefully pry the closing tabs open. Remove the small cover, and set it to the side.

What kind of wiring do I need for a Cummins 5.9L engine?
The 60250 harness is a complete wiring system for the turbo diesel injection systems on 2003-2005 Cummins 5.9L engines. Only the factory ECM is to be used with this harness. This harness includes all wiring that is needed by the computer to run and control the turbo diesel injection system.
Where is the ECM on a painless car?
Look online at www.painlessperformance.com for more information. The ECM is pre-mounted to the driver side of the engine block. If you move the ECM anywhere from the factory position, the 60250 harnesses will not properly fit. The fuse block is weather proof by design and should be mounted in the engine compartment.
