I have to tell you i always remove the negative terminal when i install anything and this was no exception.

HOWEVER, i did reconnect it just to test everything before completely re-assembling the dash to find out that my headunit wasn't working properly and needed to take it all apart again...

Thinking back on this, i think i forgot to plug in the AC control switch at first and installed it after my battery was reconnected. My bet is this is where i F'd up and caused the SES..

Anyways, im waiting for my backup camera license plate light mount to be delivered so ill take off the negative terminal when i do that and reconnect it properly when i finish. Ill let you know how that goes. Thanks again!!
