Nope. One is a relay, the other is a control module. The control module TELLS the relay when to operate.
Constant Control Relay Module
The Constant Control Relay Module(CCRM)interfaces with the Power Control Module(PCM)to provide control of the cooling fan, A/C Clutch and fuel pump. The module also includes the electronic engine control(EEC)relay to provide power the PCMThe CCRM is a set of 4 relays in one module. The relays are :1. Relay for the PCM (Powertrain Control Module)2. Relays for the high and low radiator fan speeds.3. Relay for the fuel pump.4. Relay for the Air Conditioning clutch on the compressor.

The Powertrain Control Module is the vehicle's computer
The power control module (PCM) is the brain of the vehicles engine functions. The relay is a module as part of its power supply circuit.
The CCRM is a set of 4 relays in one module. The relays are : 1. Relay for the PCM (Powertrain Control Module) 2. Relays for the high and low radiator fan speeds. 3. Relay for the fuel pump. 4. Relay for the Air Conditioning clutch on the compressor.
Power Control Module
PCM means Powertrain Control Module A relay is a low voltage switch
The 2001 ford Mustang uses a Constant Control Relay Module. This module is a sealed unit and contains the AC relay.
