[6pack] Trying to convert my '74 TR6 to electronic ignition

[Bob Danielson]

Jim,
You're talking about the ballast wire that goes from the coil to the
ignition switch. It's a pink/white wire (I think the cover is cloth-like
instead of plastic) that has a solid core which is not copper. I forget what
it's made of. One end is at the coil and the other end ties together with 3
white wires (fuse box, voltmeter & alternator warning light) and attaches to
post #3 on the ignition switch. You can find an updated stock diagram here
http://www.advanceautowire.com/tr2506.pdf  Just scroll down to your model
year. 

Having said all of that I'm not sure if you can just remove the wire and add
a new coil. I let the other experts answer that part of your question.

To do this, I'm trying to locate the resistor wire that tames the positive
side of the coil down to 6 volts.  I would like to use the coil that takes
12 volts in.  This TR6 has an old and fairly stock wiring harness and
currently has two wires going to the positive side of the coil.  The wiring
diagram only shows one wire going to the positive side of the coil so not
sure what I have here.  

Is the resistor wire just the one going from the fuse block to the coil and
if converted to a standard wire, would my coil have 12 volts to it?
