Wire Retention And Routing - Ford C-MAX HYBRID 2013 Modifiers Manual

2-18
• Route wires to avoid metal edges, screws, trim fasteners and abrasive surfaces. When such
routing is not possible, use protective devices (shields, caps) to protect the wires. Cover metal
edges with a protective shield and fasten the wiring within 76 mm (3 in) on each side of the
edge (see figure below).
• Route wires to provide at least 76 mm (3 in) of clearance to moving parts in their extreme
movement location, unless positively fastened and protected by conduit.
• Avoid wire routing without conduit in areas where temperatures exceed 82°C (180°F). Heat
insulation and heat shields must be used on the wires routed in high-temperature areas.
• Make certain that all underhood or underbody wiring is cross-linked polyethylene
high-temperature insulation wire 135°C (275°F) (minimum rating) consistent with SAE
specification J1128 Type SXL wire. Normal PVC wire must not be used in underhood or
underbody applications.
• Make sure all ground locations are readily accessible for installation, service and verification.
• Do not place ground attachments in high-splash areas.
• Underhood/underbody wiring must be routed in conduit for protection. Minimum conduit rating is
177°C (350°F).

Wire Retention and Routing

Use the following criteria to determine the location of retainers:
• Size and weight of wire bundle.
• Holes with poor accessibility that prevent installation of locators.
• Movement of wires that can result in abrasion, squeaks and rattles.
• When wiring is routed between 2 members where relative motion can occur, the wiring should be
secured to each member with enough wire slack to allow flexing without damaging the wire.
• Wiring exposed to weather must provide a drip loop to prevent moisture from being conducted
into the device through the wire connection (see figure below).
