Replacing stabilizer legs switch

[bweigele]

I have 2021 Flagstaff 26rkbs and am replacing the switch for the stabilizer legs. My new switch has a yellow, red, blue and black wire. My old switch has 2 white wires, 1 red/white and 1blue/ white wire. Has anyone run into this before? Not sure which wire goes where. I'm guessing the red goes where the red/white wire goes. I know the black is the ground on the new switch but don't know which wire is the ground on the old switch. Hoping I don't have to crawl around under the trailer. 2 bad knees and 2 hip replacements makes it difficult. Thanks for any help.
