F. Use rubber grommets whenever wires must pass through holes.
G. Cover all full time hot or accessory and ignition hot wires with approved loom.
H. Avoid routing wires in contact with fuel lines or plastic components.
6. Always be sure ground straps are replaced when any work is done on engine components. The
alternator must have at least a six (6) gauge strap. The engine must have one strap, engine block and
transmission. (Use bolt that mounts transmission to rear face of engine block.) Allow slack loop for
engine motion. Use external star tooth washer between cable and frame.
7. Do not “splice” into existing wires, instead route wire full length to appropriate source.
8. If accessories must be added, relays may be required; check installation instructions thoroughly. Use
bank of circuit breakers in the electrical panel unless the accessory must be on during cranking, in
which case the “hot bar” should be used.
9. Always use insulated rubber boots over hot six (6) gauge wiring on alternator, ammeter shunt or
junction blocks.
