The common wire is the positive. It should actually be pink. Also, there should only be two other colors if it's a 95, as they are not SFI, they are batch fired. Cylinders 1 and 4 are on the same circuit, and 2 and 3 are on the same circuit. On mine, the colors are pink (common), green, and gray. However, as long as you know that your common is your positive, you're all set.

so the common wire is always the positive??

Not always, no, its just easier to switch the ground than it is to switch the positive side.

And by switch I mean turn the ground on/off with electronics in the ECU.

Its the pink/red that is positive, and the other one is negative, however which way you have it on the injector does not matter.

not like it really matters , the injectors dont care which wire does what , all they know if on and off
