Hei distributor swap

I have a 85 bronco with a 351, 5.8l. I want to swap to a GM hei distributor. There is a red and green wire on the old coil. Once I spliced on to new pigtail for the hei, the tach pegged all the way over. Does any buddy know how to correct this so I can use my stock tach ?

Your missing the ground wire to the hei believe black with green there will be two ground wires for the hei to make the tach work. I have more details if you can’t find it text me 7146141097

The distributor cap should have markings telling you how to connect. You need two grounds internally, and external ground, positive power (with key on) and coil (-).
I don't have any images on me now but can circle back. Post photos and I'll help.
