INSTALLATION
The Pro-Flo XT Main Harness is divided into two pieces, the engine harness and chassis harness. A bulkhead connector is provided as a pass
through firewall connector.
1.
Inspect the Main System Harness, making sure that all connectors and grounds are properly in place.
2.
Edelbrock strongly recommends mounting the Pro-Flo XT ECU in the passenger compartment to protect it from possible damage. A 37-pin
bulkhead connector has been supplied to simplify wire routing. Mounting this connector will require drilling an 1-1/2” hole in the firewall,
along with four 3/16” holes for the mounting bolts (#6 machine screws are recommended).
NOTE:
The harness ends include strain relief collars that extend several inches from the bulkhead connector. Verify that sufficient
clearance from any exhaust piping or other hardware is available BEFORE drilling.
NOTE:
Start the screw holes with a pointed punch or small drill.
3.
Mount the plate so that the large coarse threads protrude through the hole in the firewall into the engine compartment. The square
mounting pad should be on the cabin side of the firewall. Use RTV to seal the plate to the firewall.
4.
The engine harness was designed to be routed underneath the plenum area of the Pro Flo XT intake manifold. See photos and diagrams for
additional information.
5.
The heavy ground lug with black wires should be bolted to the rear of the cylinder head. Be sure the connection is clean with without any
corrosion. The heavy power lug with the orange wire should be connected to an uniter12v source such as the positive terminal on
the starter solenoid.
6.
The pink wire with a black stripe should be connected to a sw12v power source. It should hot in both the start and run positions.
See the photos and diagrams that appear elsewhere in this manual for further details.
