How to replace the Power Distribution Relay attached to the wire harness on Cadillac DTS?

Before you can change out the Power Distribution Relay connected to the wire harness, use the Master Electrical Component List to figure out where it is located. After that, remove all fasteners that are securing the relay and carefully take out any CPA devices or secondary locks, taking care not to damage the relay or the wiring harness if either fasteners or tape are used. With the relay removed from the connector, put the new relay onto the connector, put any CPA devices or secondary locks back on, and hold the relay in place using the original fasteners or tape.
