Hey Terry, thanks for reaching out!

Yes, the Demco Stay-IN-Play Duo # DM86VR wiring can be spliced into the Curt Custom Tail Light Wiring Kit # C96JR but you'll need to add a Diode # RM-690 to each circuit to avoid backfeeding.

So this will work, but without using the diodes you run the risk of the backfeed happening.

An alternative wiring harness that has a module built in to help prevent backfeed is the Hopkins Custom Tail Light Wiring Kit # HM39VR.

Does that help at all?

Hey Terry, did adding the diodes with your Stay-IN-Play Duo and Curt wiring kit solve the backfeed issue? Knowing how that setup worked could really help others wiring their towed vehicles the same way.
