Question:

What is the diameter of the main barrel body? I have already bought one plug and wired it only to find it is too large for the jack on the vehicle. The connector on the vehicle I need to hook up is 13/16 The trailer-side connector I have measures 7/8 inches and does not fit.

Expert Reply:

The Pollak Heavy-Duty 4-Pole Round Pin Trailer Wiring Connector part # PK11409 is 13/16" diameter on the end where it would plug into the vehicle side connector. If I were you, I would order both this and the Pollak Heavy-Duty 4-Pole Round Pin Socket part # PK11410 to make sure I have an exact match as these two connectors are designed for one another. If the trailer side connector that you have works with the above which it should as they have the same 13/16" diameter then you can return the extra vehicle side connector.
