Which Wire is 10 Gauge in the Jacketed 7-Wire Trailer Wiring, # 127C500-1


do you know which wire in this bundle is the 10 gauge, as i understand the description 6 are 12 gauge and 1 is 10 gauge. i am hoping the 10 gauge is the brake line blue? thanks!

I went out to the warehouse to examine the wires contained in the jacket 7-wire, # DW04914-1. The white wire is actually the 10 gauge wire and the others are all 12. You would still use the white wire for the brakes if you wanted but traditionally, though there is no standard, white is the ground. Or, if you wanted separate blue wire, 10 gauge, you could use # 10-1-1. Both of these wires are sold in 1 foot increments.
