29.1 Semi Assembled Loom Construction
The engine bay is a harsh environment for wiring harnesses with oil, water, solvents, high
temperatures, high vibration, and high electrical noise. The semi-assembled wiring harness is made
from automotive grade cable and the shielded cables are already made-up at the ECU connector to
prevent electrical noise problems.
The following should be noted when constructing the loom;
The ECU should be mounted away from sources of extreme heat (such as exhaust), and away
from direct water spray.
The connector terminals should be either crimped with the correct tool or crimped and soldered.
The looming material holding the wires in the loom should totally cover the wires to prevent
chaffing of the wire insulation.
If the loom is to go through panels, grommets should be used.
The loom should be tied to mounting points using cable ties or p-clips to limit the additional
stresses of the loom moving.
