Replacement 4-Way for Karavan Boat Trailer with 8 Wires
Updated 01/27/2026 | Published 08/19/2024
Question:
I have a Karavan boat trailer and the 4-pole flat trailer connector has failed. This connector has 3 brown wires , 3 white wires, 1 green, 1 yellow that feeds into a 4-pole flat connector. One of the poles failed and came out of the connector. I am not finding a replacement 4-pole flat connector with that wire combination. What are my options? Do you have a 4-pole flat trailer connector with that wire combination? Or will I need to go with the junction box approach?

Hi Ross; you have some extra running light and ground wires on there right now which isn't uncommon. You can still use the Wesbar Wishbone Wiring Harness # 002402 you were looking at, you will simply need to tie the ground wires and the extra running light wire together when you connect it. You can go the junction box route as well using # PK52248 which may make it easier to organize everything.

Hey Ross, how did things go with the Wesbar wishbone wiring harness on your Karavan trailer? Did tying the extra ground and running light wires together work out as expected? Your update could make it easier for others sorting out similar wiring setups.
