Update:

Today i cleaned out all the connectors and the trunk itself. I will be heading to Houston tomorrow ( 2 and half drive) to go buy the central module and vacuum module. I will also be buying the connectors with it so that i don't need to worry about any problems later. Since am going there is there something i might need to purchase or i should be concern about? The car was in a collision in the front end. I finished cleaning late and it was dark to take picture (sorry about that). I will do it tomorrow. The inside of the circuit board is really bad. Some of the components are already rusted and already fell out!

Thank you all.
