I bought a new master switch because mine burned. The side mirrors, passenger and back door windows don’t work only drivers front works. I had to change the plug and I had to splice and put new pins on. I may have switched one by accident. I am looking for the wiring diagram that goes to the plug that controls everything. There are 5 wires coming into the black plug.

Hi,

Believe it or not, there are two different designs. They are identified by RPO numbers. However, the one thing I noticed is there are 5 wires going to the master switch with RPO AN3/DL3. So, that is what I attached.

Take a look at the schematic and identify the wire colors on your connector to confirm.

Let me know if this helps or if you have other questions.

Take care,

joe

See pics below. Note: I cut the schematic in half to make them readable. I did overlap them.
