Well yes a ground goes to the ground to help ground something out..... lol..but this black ground wire doesn't reach the ground.. so im assuming it grounds something in the engine bay:poke::p
The green, ground wire, that goes to the tach is supposed to go to the negative terminal of the coil though. So Im assuming its supposed to make the ignition coil fire until I start cranking the car over and at that point it stops..
