Wiring a Autometer tachometer with MSD
Where do I connect the green wire for the Autometer tachometer with msd in the car. I read you can't connect to the negative side of the coil with a MSD box. I know there is a connection on the msd box itself but ive hidden the box under the battery tray and am looking for another way. Can I connect the green wire directly to the hei utilizing the tachometer side? Maybe with a pigtail or just a female spade? Please help.
