Installation Instructions for Circuit Protected Converter

Part Numbers:

• 119178

Wiring Access Location:

• Not specified in the document.

Tools Required:

• Drill (3/32” Drill Bit)
• Wire Crimpers
• Philips Head Screwdriver
• Test Probe

Step-by-Step Instructions:

1. Using a circuit tester, carefully probe one wire at a time to determine vehicle functions.

   • Caution: Do not probe across two wires or across a wire and vehicle structure to avoid damaging electronic components.

2. Disconnect and isolate the vehicle's negative (-) battery terminal.

   • Warning: Follow all warnings and precautions printed on the tow vehicle’s battery.

3. Attach the trailer wiring to the vehicle as shown in the illustration using splices.

4. Locate a suitable grounding point.

   • Caution: Verify what is behind any surface before drilling to avoid damage or injury. Do not drill into exposed surfaces.

5. Mount the circuit-protected converter near the left tail light in the trunk or on the frame rail under the vehicle.

   • Mount with the wiring directed downward or sideways if downward is not possible.

6. Reconnect the vehicle's negative (-) battery terminal.

7. Testing Procedure:

   • Attach the ground lead of a circuit tester to the exposed ground terminal of the 4-flat end.
   • Activate the tow vehicle’s left turn, right turn, tail, and stop lights one at a time. Test each to confirm proper functionality.
   • Warning: Ensure all connections are complete for proper function. Test installation with a trailer or test light.

8. Secure all loose wires with cable ties.

   • Warning: Do not overload circuits to prevent fires. Adhere to these limits:
     • Max stop/turn light: 1 per side (2.1 amps)
     • Max tail lights: (7.5 amps)

Hardware List:

• Not detailed in the document.
