My ex once told me I have a perfect face for radio.

ok so thats how you test the wires

Let me double check If the wire in the car is postive or negative I always but the black lead from tbe DMM to the Car's ground and the red lead from the DMM to any wire?

I hope I got it correct, I will go and test out the locks

What about testing for a postive Do I still put black to ground and the red to the wire does it matter if its a postive or negative?

I probed the wire but its the same when its lock and unlock

it shows 12v+ you said something about setting it to a low setting how can I do that my meter goes only to 20.

If nothing changes when you press a button, you're testing the wrong wire. Keep looking.

I said use a low setting if you're testing resistance to ground. If you're measuring voltage use the 20v setting.

If you can't verify with a meter that's the wire you need, can you explain how you know it is the correct one?

the wiring chart says relay above pedal

and thats the only color in the area to be GRAY/BLACK.

I will double check on it later

Don't take any wiring charts for granted (wiring colors are often wrong). I use them as a starting point, then verify my wires with a meter or logic probe. You're probably in the right area, but if you don't see a different reading when you press the buttons, you're on the wrong wire. You maybe on the wrong side of the relay's coil.
