LOC T-Harnesses have vehicle specific applications.
Please visit AxxessInterfaces.com for the latest and up to date application information.
TOOLS RECOMMENDED
• Digital Multi-meter
• Test Tones
Things to Know
• LOC T-harnesses are installed at the radio and designed for non-amplified vehicles. You can find dash
disassembly instructions from the Vehicle Fit Guide on AxxessInterfaces.com
• It is recommended that a polarity tester and tone generator be used before connecting your
aftermarket equipment.
• If your vehicle doesn’t have an accessory circuit your LOC T-Harness will not have an accessory (Red)
wire in the harness. Refer to the AX-LOC instructions for remote turn on options. Some vehicles
require the addition of load resistors, there are multiple options available. We recommend AX-LR20,
AX-LR39, and AX-LR60.
• Proper termination of loose wires is required.
