Question:
Can I have a snowmobile trailer hooked up to the factory bumper harness and a snowmobile sled deck plugged into the bed harness at the same time?

Hey Steve, yes with 7-way kits like the part # C53CR that you referenced that adds a second 7-way to a vehicle both of them are active so they both can be used at same time like you asked about. Only issue is potentially you might overdraw the circuits if there's too many lights being powered. Does your trailer have LED tailights by chance? If any of the lights are LED that wouldn't be something to worry about.

Hey Steve, how did things go using both the trailer and sled deck with the Curt 7-way harness? It’d be great to hear if the lights worked smoothly without any power issues. Your update could make it easier for others running a similar setup.
