Found these unplugged in the trunk. Does anyone know what they are and if they should be plugged in? Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login
The connectors connect to the pushbuttons (in the trunk) which are used to read codes from the Check Engine Lights (CEL 1-4, and CEL 5-8) on the dash. There are two pushbuttons, one for cylinder bank 1-4 and another for bank 5-8. I think they are normally plugged in, at least mine have been.
