Pertronix 1381a

Called them back said it has nothing to do with the plugs just wires they were not sure why someone said that, but to make things more confusing the guy told me today black wire on negative side of coil red on positive side of coil(from the kit/distributor) then run a switched 12v power wire to the positive side of the coil as well ,this seems to me I’m bypassing the resister which the instructions say not to do I told him my coil is 1.5 ohm and he said that’s right it matches the 1381a. How could something so small be so confusing ,fig3 above looks like nothing like he said.
