Help with Trunk Lock Issue

My trunk lock started leaking air so i fixed it but then it broke alltogether...i replaced the whole locking system but now it does not work right...it does not leak air...it opens via button or remote but the self closing does not work...neither do the lights in the trunk....i think i narrowed it down to the switch that tells the unit that the trunk is partially closed...its a blue connector on the side of the unit...the switch is ok...when you click the lock into its first position where it should start self closing the switch goes open...i need to know where that cable from that switch goes to...i have wis/asra but cannot find anything i can use...any of you guys know what to try/do next ? or where to look for a wiring diagram ?

Your help would be appreciated.

PS: i already disconnected the battery to do a full reset....the problem persists
