where the stock coil?

why this coil?

 

You still running points????????? should have taken photos before pulling wires off

 

this is a pertronix Flame thrower 3ohm? or 1.5 ohm?

 

the big blk/wht wire will go to the ballast resisitor. You can tell by putting key to ON it will have 12volts.

the the connector that has 2 wires *under the center coil wire in 1st photo. the left side wire goes to the bottom side of the ballast the the lug with 2 wires goes to + side coil.

 

the rest there is a wire diagrame to finnish the rest. or just route a wire ffrom the main set of points to the - side coil

 

 

unless you know what your doing leave the stock coil in there. if you have a 3 ohm coil then you wouldnt need the ballast but might be harder to start compared to the stock set up

That looks like an aftermarket ballast resistor. Like the old Dodge trucks had. I just got rid of one identical to it. You can buy a coil like you have for an electronic ignition for about 26 dollars. It makes a much stronger spark if you can find an EL dizzy distributor. 

 

Gotta be the number 1 over-all improvement you can do to the old Datsuns,
