Does anyone happen to have a diagram of a fuse box for an 88 Monte Carlo ls INCLUDING what is normally wired to the ignition ports on the left side of the fuse box?

Got this diagram of an 87 off the Internet and it should be similar. Hope it helps.

These pictures do help some, but what I really need to know is what these two ignition ports on the left side are normally connected to.

If I remember right that connector on the left, the c209 on the diagram I posted has mostly the wires that go to the back of the car and has the fuel gauge integrated in it. I am just guessing but it might be for rear lights, backup lights, any wires to the gas tank?

According to my manual the pink/black wires are >trunk release and >rear defogger.
Let us know if this helps.
I'm guessing the position does not matter because, I think, it's a 12V switched source -ign on = 12V

I was just going to post this. I found some diagrams on the Internet and some cars had cruise control also in that position where the pink wires are.

I guess the best way to find out what they are is unhook one and see what does not work? I use to do that on a few cars we bought because of the previous owner hacking the electrical system and only way was to unhook ans see what happens. These were pre computer cars.
