Thanks, I just want to double check my connections before I make the connections
as already noted, it is highly recommended to use a CORRECT for year/make/model interface adapter, then there is no need to verify anything but what is on your headunit
the adapter will be marked accordingly. the rpo codes in the glove box tell you everything you need to know.
there is a difference between using a $10 adapter and a $50 adapter

We should differentiate between a simple pigtail that would connect the head unit to the body wiring using the correct connector, vs. an adapter that allows steering wheel controls to work. First one is inexpensive, second one can cost some $$.
