Installing the Main harness and ECU
To install the system harness, you should first layout the harness in your vehicle to
determine the best layout and routing for your application. Of primary concern, is the
mounting location of the Engine Control Module (ECM/PCM), relays, interface connectors,
and system fusing.
You may choose to mount the ECM inside the passenger compartment similar to OEM
practice. However, the ruggedized ECM also gives you the option of mounting it under
hood. Layout the harness with the appropriate injector connectors corresponding with the
injectors on the engine. Within the available length of the harness, determine potential
mounting locations for the ECM and relays.
Improper installation may cause system
failure and void your warranty.
To mount the ECM and relays correctly, the following rules should be followed:
1. Keep ECM, components, and wiring as far away from heat and exhaust parts as
possible. You may need to install heat shields over certain areas in the engine
compartment to prevent excessive heat from reaching the electrical components.
2. Mount the ECM and relays using only the grommets, bushing's, and washers
provided. Use the Edelbrock ECU mounting bracket shown below for proper
mounting and flexible orientation. These parts are specially engineered to insure
proper isolation of the ECM. Locate the fuse pack so that it can be accessed
conveniently. The fuse pack is shown in Figure 10 below:
