My 2005 Toyota RAV4 has 2 Key wires and a ground for SWC, while my new head unit with built in interface has one dedicated key wire.
I grounded the yellow wire and connected my car’s Key1 to the unit’s Key wire, leaving out the car’s key 2 wire which corresponds to the 5th “mode” button on my steering wheel.
Can I twist my car’s Key1&2 wires together and connect to the unit’s Key wire so that I can use that last missing button, or is that a bad idea?
