Normal Operation
The trailer tow parking lamp relay coil receives voltage through circuit CLS30 (VT/WH) when the vehicle parking lamps are illuminated. The trailer
tow parking lamp relay coil is grounded through circuit GD120 (BK/GN). The battery junction box (BJB) fuse 8 (20A) supplies voltage to the trailer
tow parking lamp relay switch side. When the trailer tow parking lamp relay is energized, the voltage is routed to the trailer tow connector through
circuit CAT11 (BN).
