Can Wire Be Added to 7-Way Wiring To Increase Length


Hi The green wire in the 7 pin harness is ½ shorter than the other 6 wires, and keeps pulling off the screw terminal inside the plug. No right turn light on my travel trailer Can i pig tail a 16 gauge wire onto the green? I’m thinking of making the pigtail connection about a food away from the plug? We’re travelling across the country right now and its the weekend so can’t find anyone to install a new plug.


Expert Reply:

Yes, you can add wire to lengthen the short wire you have on your 7-way so that it stops pulling itself out. We don't carry 16 gauge wire but we do have 12 gauge as part # 12-1-1 which is sold by the foot.
