Default Installing aftermarket remote entry.

Have a 2007. Remote locks stopped working on fob. decided to install an aftermarket unit. Understand it is a type b negative but am having a devil of a time finding the right wires to lock and unlock. I have seen light blue and tan, light blue and dark blue but none of the suggested combinations work. Anyone know what the correct ones are or am I missing something else?
