Picked up a pair of heated seats and switches for my sons project

I have a wiring question that I hope you can answer

There are 5 wires to each of the switches
Both have
Green with red stripe
Black with yellow stripe
Black
Red with blue stripe

One has
Red with white stripe
Other has Blue with red stripe

I am assuming
Black will be ground on both
The red with white stripe and the blue with white stripe will be the power going to the heated elements.

What are the rest?
I will run a relay with a fuse, just curious to know what the wires are from. In my head there should only be one wire that is running positive to the switch so 3 wires is confusing me.

Also how often do the "lights" on the switches burn out?

Thanks in advance
