Wire Gauges Used in Deka Jacketed 6-Wire and 7-Wire Trailer Wiring

Question:

On the 6 way trailer wire harness that you sell....the one with green yellow brown black red and white in a black sleeve, all the wires seem to be a 16 gauge. I thought that the brake wire normally requires 12-14? Thanks for the help in advance.

The wiring harness kits we offer for your 1996 Ford F-250 are all 4-pole types like # 118316 and the others shown on the linked page. The include a white ground wire, yellow left turn/stop wire, green right turn/stop wire and a brown running light wire.

6-wire jacketed cable like # DW04906-1 from Deka does use all 14-gauge conductors. Their 7-wire cable, part # DW04914-1, does use heavier 12-gauge wires for all except the ground, which is a 10-gauge. Both meet SAE J1128 specifications for use with circuits up to 50 volts.
