Bushtec trailer wiring harness

[dag62]

I have a friend who has a 2019 RT. They just purchased a used Bushtec trailer and the BRP hitch and wiring harness. My question is do they make a 4 pin square (Spyder side) to 5 pin flat (Bushtec side) adapter? Or do they need to buy the Bushtec wiring harness for the Spyder?

Thanks, Dean

The 4-pin connector combines the turn signals and assumes the trailer does not have separate turn bulbs. I wired up a simple/emergency 6-pin but both brake and turn use the amber lights on the Bushtec. Best to get and install the Bushtec harness.
