I am sorry for the long wait

the Tan wire you want should turn on and off a ground as the door latch is latched and unlatched

its best to be 100 % sure to just test the 3 Tan wires and only 1 of those Tan wires will switch a ground off and on as the door is latched closed and then open

OR you can just go behind the left inside fuse box and connector C4 as seen in this picture terminal E ( Tan wire ) is the one you want
