JaSSon Posted May 16, 2004 Report Share Posted May 16, 2004 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.

MrMeanGreen Posted May 16, 2004 Report Share Posted May 16, 2004 Do you have a shop manual for the car? Trace the electrical connections to your ignition and it should tell you which is which. Quote Link to comment Share on other sites More sharing options...
Mensan Posted May 16, 2004 Report Share Posted May 16, 2004 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.
