So I'm trying to wire a similar switch and wanting to make sure I've got it all correct. So power I'm good with. The dash light circuit is what I need clarification on.

Red(power) - Planning to use an add-a-fuse to the box to power on with ign
Black (ground) - This is the one that needs to be spliced to the white w/ green stripe wire on the DAC plug
Yellow (dash light circuit) - Spliced to green wire from DAC plug

Is that correct?
The solid green wire from the plug is the backlight circuit?
Is that powered only when the interior backlighting is on or is that function controlled through the ground circuit?
Mine does not have the air lift suspension. Could I use the plug for that so I'm not cutting up a functional DAC wire?
