4) You can convert a 268 kit to a 684 kit by simply cutting the connectors on the kit that connect to the radio and speakers.
Here is my theory. I should be able to use the 268 kit without recoding the radio by putting the switch on the Alpine amplifier to position #2 instead of position #1.
I hope to verify this soon.
I would like to know your results in switch position #2 as well, as it does not make any sense to me that a different harness connector
is sufficient to warrant an OEM HU coding
Something else must be going on here.
