    I'm driving a 2016 Prostar and I am trying to take out a "Spare" switch so that I can hook some additional lighting to it. The harness pops off of the back and is super easy to get wired, but I need to test the switch points to find the proper circuit. Can anyone help with this?

    The spare switch triggers a relay. You don't wire lights to the actual switch. There should be a power wire from the relay that you connect your accessories or lights to. It should be a 12 gauge green wire numbered A14SAD or A14SBD. This is located right in the breaker panel in front of the passenger seat.

    You are absolutely right! I feel like an idiot. I never thought to feel relays while flipping the switches. I have located them and you are 100% correct. At the risk of doubling my idiocy, any chance you know where to connect a ground in the panel?

    Any solid white wire is a ground wire in Internationals, you can tap into one somewhere there as long as it is the proper gauge size. I have seen guys just drill into that steel cross bar pipe and ground to that too.
