Tacoma Trailer Lighting Problems
The Toyota Tacoma is a truck designed to work well with hauling trailers. Like any vehicle on the road, the truck and the trailer must have proper tail light illumination for overall safety, but there can be electrical problems.
Function
A trailer, attached to a Toyota Tacoma, uses a wiring harness converter box for its extra electrical needs. Without this power supply, the Tacoma could possibly have electrical failure from the power surge load.
Considerations
For model years 1999 to 2000, the Toyota Tacoma had a recall of its converter box. With its improper sealing, the box was susceptible to water infiltration, causing an electrical short and no power to the trailer lighting system. Toyota replaced the box and rearranged its placement on the vehicle to prevent excess water exposure.
Significance
Make sure that the lighting system is properly grounded to the frame of the Tacoma. Without a secure ground, the lighting system can malfunction by surging when both the vehicle and trailer have their brakes applied.
