Keep-Alive Memory (Kam) Power; Equipment Grounding Guidelines; Wire Insulation - Ford FUSION HYBRID 2013 Modifiers Manual

2-12
• Adherence to the above guidelines is not to be construed as approval by Ford Motor Company
of any specific revisions or additions to the vehicles original electrical system.
• Document all revisions to the electrical system and place with the vehicle Owner's Literature.
Color code and/or label all revisions or additions to wiring.
• Disconnect the negative battery cable of vehicles stored on site to reduce the possibility of
draining the battery by lights or other equipment.

Keep-Alive Memory (KAM) Power

The electronic motor and/or transmission control modules and the HVTB BECM require low battery
voltage (12 volts) to be supplied at all times to maintain the keep-alive memory (KAM). Keep this
in mind when installing load disconnect switches or solenoids.

Equipment Grounding Guidelines

NOTICE: Do not use/modify any of the high-voltage system grounds or damage to the
high-voltage components may occur.
• Do not ground the body to the transmission or transmission crossmember. Ground accessories
to the chassis or the vehicle battery.
• Splicing into circuitry relating to the electronic engine and/or transmission control systems is not
acceptable because of the adverse effect on the electronic system operation.
• Adequately protect electrical connections exposed to the elements.

Wire Insulation

• Polyvinyl chloride (PVC) rated at 90°C (194°F) is the standard wire insulation that is acceptable
for inside body use but is not acceptable for underhood/underbody wiring.
• Hypalon insulation should be used on links only (Ford specification ESB-M1L54-A).
• Cross-linked polyethylene (XPLPE or SXL) rated at 125°C (257°F) is the required insulation for
underhood/underbody applications (Ford specification ESB-M1L123-A).
• GXL can be used as an alternate wire (Ford specification ESB-M7L85B) as long as the
concentricity specifications are met. To provide a water-resistant seal in conjunction with crimp
connectors, a Duraseal® crimp connector is recommended since it is designed to account for
outside wire diameter that is smaller than the present SXL wire.
