You are correct the Kwikee Electric RV Step Complete Assembly is a 4 wire.
The included 4-way plug fits into the existing wiring harness on your RV. Most vehicles should have this wiring already set up. In the event that your RV is missing the wiring, a 4-way pigtail is included to help you hardwire the unit to your RV. view full answer...

I recommend using the MORryde StepAbove RV Steps for 21-3/4" to 22-1/4" Wide Doorways - 2 Steps # MR86RR, which I was able to confirm with my contact at MORryde will work on your door with 22-1/2" between the flanges.

Ours will fit on either side of your steps so you can get them installed on your RV. I have attached a photo of our kit that you can check out. view full answer...
