WIRING CONNECTIONS
• Before making your connections, plan entire wire routing inside the
vehicle prior to staring the installation.
There are few acceptable ways of making a wire connections:
Solder connections, strip and tape connections and crimp connectors.
When soldering connection be careful not drop solder on interior dash
panels. When doing strip and tape wiring method, best way is to strip
insulation off a wire, make a hole in a wire and route a wire thru a
hole and then use tape to insulate. When using crimp connectors
make sure not to crimp to insulation as this may cause wire to break.
• Low quality electrical tape is not a reliable insulator. It often falls
off in hot weather, always use high quality electrical tape.
• Never twist and tape wires together without soldering.
• Never use fuse taps as they can damage fuse box terminals.
• If you use wire-tap connectors such as T-Taps, avoid using them.
These connectors are inferior in quality and should be avoided.
