You do not have to change harness...
On my bugeyes switches i could remove the female connector (part attached to the actual switch) and replace the connector in the 05-07 switch with this one.
This leaves you with a " hybrid " switch setup that plugs Into your 02-04 harness
Everything works fine for me so far the only thing I haven't done is extended my mirror switches.
OK, I kind of understand, I could probably figure it out though.
What would I need? Just the door cards and switches? So not the plugs or harnesses or pigtails? I can make my current ones work?
