How can I tell if my ignition system on the Mustang ('65 289 ) has a ballast resistor?? Where is it and what does it look like. (I'm installing the Pertronix II system...)

I'm pretty sure it's in the dizzy and it looks like this.

my 71 has a "resistance wire" in the firewall/ under the dash that is used liek a balast reistor. My ignitor went on with the instructions of " without a balast resistor" and it worked perfect. My coil also said " use without a resitor" so i figured my car didnt have one to begin with. but then again... mines a 71-Jon

Just get the Pertronix resistor. It isn't 100% mandatory but it's worth it.

Balast resistor in a 65? Never heard of one. The only resistor you have in your ignition is the pink resistor wire. You do not need a balast resistor with electronic ignition.

Yea - I did a search and found an article by Ford Mag that showed it was a straight forward installation. I went back and checked the ignition section of the manual and it showed no ballast resistor but I just wanted to be sure!
Thanks guys!

Thanks for the MM rendition of how to install the pertronix. I will add that to the FAQ, so it will be one of three methods. It ain't a big deal though. I put mine in in about 20 minutes even with going to the ignition switch and eliminating the pink resistor wire.
