GENERAL
All devices should be mounted in accordance with the manufacturer’s in-
structions and securely fastened to vehicle elements of sufficient strength
to withstand the forces applied to the device.
WIRING
Do not use insulation displacement connectors (e.g. 3M Scotchlock type
connectors). Route wiring using grommets and sealant when passing
through compartment walls. High ambient temperatures (e.g. under-hood)
will significantly reduce the current carrying capacity of wires, fuses, and
circuit breakers. Use “SXL” type wire in engine compartment. Minimize
the number of splices to reduce voltage drop. All wiring should conform to
the minimum wire size and other recommendations of the manufacturer
and be protected from moving parts and hot surfaces. Looms, grommets,
cable ties, and similar installation hardware should be used to anchor and
protect all wiring.
Particular attention should be paid to the location and method of making
electrical connections and splices to protect these points from corrosion and
loss of conductivity. Ground terminations should only be made to substantial
chassis components, preferably directly to the vehicle battery.
The user should install a fuse sized to approximately 125% of the maximum
amp capacity in the supply line and each switched circuit to protect against
short circuits. For example, a 5 amp fuse should carry a maximum of 4
amps. Circuit breakers are very sensitive to high temperatures and will “false

DO NOT USE FUSIBLE LINKS, CIRCUIT BREAKERS
OR GLASS FUSES!!!
1. Choose the ideal mounting location for the Control Module. It fits into any
standard vehicle console that is designed to hold radio or other electronic
equipment. It also works well when mounted under the vehicle’s dash.
