Don’t quote me cause I can’t remember
But one is for the drive mode switch but does nothing on pre 23 models but change the symbol on the display shared harness with the z1000 I believe
The others I thought where For factory heater an Likley the wiper with the full cab
I used mine for accessories
There’s 2 more under the seats that don’t go anywhere
As they where for the heated seats
That came with the 19s
There keyed power as well great for accessories
