I am preparing to change from points to the electronic system. I have been reading the I might have to remove the resister from the switch to the coil or run a new wire to the coil. Has anyone had to do this? If so, what is the better and easy way to do it?

Thanks for the help

Are you speaking of a resister wire or the physical ballest resister mounted next to the coil?

I used the points replacement device bought and used their coil (even tho this was not required) and kept the ballast resister. I called them and u can do it either way. Without the resister you do have a higher voltage to the plugs but you also heat up the coil more too. Mine starts and runs perfectly with the resister in the circuit. Never sorry I made the conversion. Good Luck

I'm talking about the wire from the key switch to the coil. I don't recall seeing a ballest near the coil. I'll have to look but I don't think it has one.

If you have a something Sixties model Ford, then the ignition resistor is likely incorporated within the wire going from the switch to the coil.  In this case, the wire from the ignition switch to the coil must be replaced to put the coil voltage at 12 volts.  I will add that the Pertronix I needs to have a resistor installed while the Pertronix II and Pertronix III can run without the resistor.

What is the battery voltage you use in your car . My car is a 6 volt system I used the module and a hot spark 6 volt coil . I assume if your battery is 12 volts you need a resistor . I am sure some on here can set it straight .But I think the battery voltage is the key 

This always gets confusing, I don't know why some people have an issue and some don't. I had an original first version of the Pertronix  and their flame thrower coil on my 57 and called them directly and was told no resistor was needed with the flame thrower coil and only needed if still using the original coil. I hooked it up to a straight 12v and ran it that way for over a year with no problem. I later installed the Pertronix II and ran 12v to it the same way, no problems either. 
I have used the Pertronix on my 66 Mustang with the original resistor wire and stock coil for 10+ years with no problem.
The only thing I don't like is the extra heat produced by the flame thrower coil because it has a built in resistor.

Do you know what vehicle you are thinking of doing this too.
