Holley pro-jection 2D Installation And Troubleshooting Manual - page 16
WARNING! Do not mount the ECU in an enclosed area. Mount the ECU in an area that will allow air to flow freely
across the ECU to dissipate heat generated by the ECU.
WARNING! When mounting the ECU, care must be taken that none of your boats other systems, such as the electrical
system, are damaged by either drilling holes or using mounting screws. Always check on the other side
of the location that is to be drilled to ensure that no damage will occur.
WARNING! Do NOT mount the ECU in the engine compartment. The ECU is not designed for the environment (heat,
moisture) present in the engine compartment. Premature failure of the ECU will result.
WARNING! The
PRO-JECTION 2D system must be appropriately grounded to ensure proper system performance and
to prevent any damage to the system.
NOTE: All connections shown MUST be made in order for the PRO-JECTION 2D system to operate properly.
1. Pick a suitable location on the interior of the boat in which the ECU can be mounted. Ensure the mounting location allows
for sufficient length of the wiring harness and clearance for connectors and the adjustment knobs on the front of the ECU
are accessible before mounting the ECU.
2. Using the ECU base plate as a template, drill 4 pilot holes, ensuring that no damage will result to any of your boats other
systems.
3. Mount the ECU with 4 self-starting sheet metal screws (not included).
11.0 ENGINE WIRING HARNESS
1. At a location near the ECU mounting, pick a suitable location on the engine compartment bulkhead for the wiring harness to
pass through. A 2” diameter hole will be required for the wiring harness. Check both sides of the bulkhead for interference.
WARNING! Before drilling, check both sides of the bulkhead for possible interference with electrical systems, etc.
Failure to do so can result in damage to one of the boat systems.
2. Use a 2” hole saw (available at any hardware store) or a punch out tool to cut through the bulkhead, as necessary.
3. Feed the wiring harness from the location of the ECU to the engine compartment. Check to ensure sufficient length of
harness is available for attaching to the ECU.
4. Slit a 2” grommet and position around the wiring harness. Slip the grommet into the 2” hole to prevent the wiring harness
from chaffing. A light application of WD-40 on the grommet will ease the installation.
5. Connect the wiring harness to the ECU. Push the plug into the ECU until the lock snaps into position.
