Okay. Now, what should I do after I see some broken abs wire on that connector? I'm still a noob at this point.

fixing wires on volvo's
 

take a cigarette lighter & heat wire & roll back wire sheathing enough to twist the wires together & solder them if you have knowledge of how to solder, if not just twist them together real tight & tape them very well. if by chance the wire is broke off right at the connector, you will have to solder wire to the connector in the plug to ensure proper connection. if need be take it to electronics repairshop, 1 of the guys would probably be glad to help you fix your broken wire, this would save you hundreds of dollars at a repair shop.

keep patching together those pesky broken wires & keep driving.;)
