Coil-on-plug question. Which wire is (-)

I am wiring up an MSD DIS window switch. It connects to the negative terminal of one of the coil packs. Does anyone know which wire is negative? There are two wires leading to each coil pack. One is green with a yellow stripe, the other is white with a blue stripe.

Most likely green w/yellow stripe is ground. That is a universal ground color. Get a multimeter and check the resistance to each wire on the other coils. It should read zero (no resistance) to the ground on the other coils.
