Converting from points to HEI

Hi i'm new here but i've already gathered a lot of great information from this site. I'm currently restoring a 1972 Chevy nova that previously had a 250 ci in line 6 with points and im swapping to a 383 with hei. From what Ive read i need to remove a resistor wire from the wiring but im still left with a different plug for the HEI coil than the previous points distributor. how and where would i get the required plug needed for HEI, and is it just a power and ground wire? also i want to add a tach which the car previously didn't have, what kind of wiring would this require? thanks for the help

As I remember this is very easy. The power wire uses a common female spade terminal and when I hooked up the tach on my '78 K-10 33yrs ago there is another terminal to hook the tach wire to. Just follow the tach manufactures unstructions on hookup. Should be easy peasy . BTW , there is no ground wire hookup. Of the two terminals on the dist, one is for power and the other for the tach. Also , welcome to the site .

Correct^^^. Female spade terminals, like a speaker uses. You can buy the correct HEI Pigtail connectors if you want. They're about $10/pr.

I'd buy the correct HEI pigtail for the power wire, since the pigtail has a plastic housing with a positive lock tab that holds it in place. You don't want that power wire falling off the HEI at the wrong time.

Or a quick walk though a salvage yard with a wire cutter. Probably get it for free at the right place. U-pull- it . Use solder and shrink tubing for a trouble free connection .
