If it's anything like the mopar fwd cars, once they went to the body module, the switches all became low amperage signal switches with the body module having the heavy relays that turn on/off the lights, cruise, wipers, etc. On one project I changed the switches out from a 90's car to the older high amperage 80's switches and that worked fine because the body computer was still doing the heavy lifting. Going the other way wouldn't have.
