Tachometer causing short
All right so it's my birthday today and naturally Ive been waiting for a tachometer and I get it in and installed, and when I hook it up to what I think is the negative post on the coil and have the switched and dash lights for the tachometer hooked up to the two spades on my fuse box
It would start up and read rpms but when the engine gets shut off and go to restart it, the engine doesn't crank and smoke plumes out of the dash. I have to go and unhook the wire that's connected to the coil and reconnect it.
So 1. What might my issue be? 2. Could someone point out what post they connected to to use these

+1 !!!! smoke equals the plastic burned off the wire , so you have a bare wire somewhere . this could lead to a bigger problem FIRE .

It sound like you added a ground wire to where it should not be.
Ya remove all tach wires for now check fuses then do as posted and look for burnt wiring.

Upon inspection, there is a red with blue stripe wire that has the plastic melted on it but all other wires seem just fine

Yes, it's connected to my ignition switch and ran along dash to I believe my starter solenoid. Turns out it melted onto my right blinker switch and would cause my truck to turn over with the blinker. Got that all patched up. Can someone please send a picture of their coil where they hooked their tach up as I cannot find how I screwed this up.
Unless, I hooked my switched and light wire up to the spade connectors in my fuse box, but I see now that they're both switched 12v. So would my light wire for the tachometer hooked up wrong really cause this?

The hookup on the coil is the same wire coming out of the firewall going to the coil that is the + side.
The coil should have a small - &+ marking on it.
You light wire hooks into the dash lights that is a white & blue strip wire on the dash plug and not into the fuse block as it would be on all the time.

what brand tachometer ?
I ask because , when i was 16 I added a Tach (cheap kragen auto parts) to my 65 mustang , my car started running funny then after a day wouldn't start . my dad helped me figure out the problem. It was the poor quality Tach . returned it and bought a better tach.

I may not add a tachometer as the only reason I was adding one was to be able to jam out and shift at a proper time. But I have quickly learned the shift spots from my speed and just feeling
