Someone changed my coil pack and mixed up the wires. I need to know if 1 2 3 is in the front by the radiator and 4 5 6 is in the back or if it's the other way around.

GM doesn't label them sequentially like Ford does. Instead on a GM V or flat engine one bank is odd the other even. On your car the front cylinders near the radiator are numbers 2, 4 and 6, the three in the back are 1, 3 and 5 Also on your car you have what is known as a waste spark system. Notice how the coil pack is labeled? See how it has cylinders 1 and 4 on the same coil? That is because it doesn't really matter if cylinder one is on the tower for cylinder one or cylinder 4. It still fires and works the same either way. So just be sure that they go to the correct coil.
