Connected to the master switch in the driver door there are four different connectors. One is a black and red wire labeled J1.
There is a grey 14 pin connector labeled J4. A brown 8 pin connector labeled J2, a black 10 pin labeled J3 and a white 10 pin labeled J7.
I believe the image you sent was J7... its a 10 pin but only 8 spots are being used.
What I am trying to narrow down, what does each connector control? It appreas J7, the one you sent, should be the windows. I am beginning to suspect the power locks are causing an overload or short of some kind (i have found the switch to be active and working but stop as soon as the locks are engaged).
Are you able to identify the other connectors? Or at least the one responsible for controlling locks?
