Keep-Alive Memory Power
The electronic engine and transmission control modules require battery power to be supplied at all
times to maintain the keep-alive memory. Keep this in mind when installing load disconnect
switches or solenoids.
Equipment Grounding Guidelines
• 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.
Terminals and Connectors
Connector Types:
• Submersible (sealed) — A connector that is capable of being immersed in water.
• Weather-resistant — A connector that will retain its sealing and connection qualities while being
exposed to adverse weather conditions.
• Duraseal crimp — A supplier trade name for a sealed wiring repair or splice.
