Question:

I am looking for a trailer connector cord set and box package for a 7 round connector. This is the connector used on tractor trailer. This connector is also used on agricultural tractors. I need a 8’ -10’ straight not Curley cord, connector, and box do that I can easily connect lights and auxiliary power on agricultural implements to the back of the tractor. Could you suggest a product? Thanks,

I believe what you're needing is the Junction Box and Installation Kit # 3430001-JBK along with the Pollak Heavy-Duty, 7-Pole, Round Pin Trailer Wiring Socket # PK11720 and then 8' - 10' of the Deka Wire - Jacketed 7-Wire # DW04914-1 (sold by the foot).

Typically the junction box is located on the trailer side of things so there aren't any kits that come with the tow vehicle connector, but this combination should do the trick! The junction box comes with all of the connections you need plus it has butt connectors you can use for any splices that you'll need to make.

Attached is a diagram of the typical wiring for a 7-Way agricultural connector but you'll want to verify that this matches prior to wiring everything up like this.
