Circuit 14 (BN) supplies power to the exterior lamps and the coil side of the trailer tow parking lamp relay. Ground is supplied to the trailer tow parking lamp relay through the central junction box (CJB). When the trailer tow parking lamp relay is energized, voltage is routed from the CJB to the trailer tow connector through circuit 962 (BN/WH). Circuit 140 (BK/PK) supplies power to the trailer tow connector for the trailer to reversing lamps. Circuits 52 (YE) (LH stop/turn) and 64 (DG) (RH stop/turn) are spliced to circuits 9 (LG/OG) and 5 (OG/LB) respectively within the CJB. Ground is supplied to the trailer through circuit 206 (WH).
