Aftermarket Tach

I have a Sun Super Tach 2.
I bought it, and never used it. Now it's time.
I see the one green wire goes to the negative side of the coil.
This coil is quite different than what I am used to seeing.
Where is the negative side? I see a two prong plug that goes on it, is it on of those? And if so, which one?

What is the info on your jeep?
Your Jeep you have on your little info panel is incorrect.
a 95 Cherokee is not a FSJ-Full sized jeep

That link should explain it all
Your tac, if like mine should have 4 wires
Red-pos battery, under the dash in the kick panel- i wired it to accessory slot
White-light, i wired mine to my dash lights so it dims
Black-ground
Green-find the green wire on the coil, tap into it.

Exactly! I just saw the new style coil, so to speak, and seen the two wires, and was wondering which was the negative wire. So I stopped before I went any further.

It is a little different than the older point style where you need the negative side, a little sensor in the distributor sends the signal via the green wire, so that is the one you tap into.
Glad i could help.

I truly appreciate it. I want to mount mine tomorrow, and fix a few other things.
