Looking For A 7 Round Trailer End Plug And Lead To Replace On My Trailer

Question:
Hi Etrailer team, Im looking for a trailer side 7 pin round plug pigtail NOT RV style, I need the round contacts. I found lots of plugs themselves, but they are not pigtails/do not have flying leads. Do you sell a 7 pin round trailer plug with round contacts with flying leads?

Hey Phil,
Since those 7 round connectors are not as common any more we only carry the plug itself like the Pollak # PK11700. This is the 7 way round pin that you have. There is no lead on the plug itself but it does take 8 to 16 gauge wire, typically 12 gauge is what I see used with this plug. Something like the # DW04914-1 would work well for you.
What kind of trailer are you wiring up?

Hey Phil, how did things go wiring up your trailer with the Pollak 7-way round plug and the wire you chose? Your update could make it easier for others trying to match the same style connector.
