Ive just bought a Mallory Unilite distributor for my 289. The instructions say that if you don't have a resistor wire in the car's wiring you need to use their ballast resistor (part #700) or the module will be slowly destroyed. I know some folks here are running Unilites, did you install the resistor or what? It's also my understanding that there is a some sort of surge protector Mallory recommends you install. Is this necessary?

Thanks all.

I run a Mallory Unilite in my '68 289 WITH a resistor for over 4 years ............no problems

Hello
Our early mustangs have a resister wire in the harness. If your car is stock no need to add another. I run the active power filter part#29351. At $32 it saved my distributor once. I was happy to replace it instead of the ignition module.

Run a resistor and the power filter. One spike and the Unilite light bulb will burn instantly. I love the distributor in my 427 and a CJ I did for a customer, but even the slightest surge will pop them without the filter.

I also have the resistor with my Unilite. No problems.

I'm running it without the resistor OR the filter on my 73 351C for 10 years and 8,000 miles. Works fine. Had a module go bad on me, though - big $$$$. The module did not go out completely - it would start and run and then once the car heated up it would abruptly die. If I had it to do over again I would have kept the stock dizzy with a Pertronix.

I've been running the Unilite on my 68 for close to 10 years now and I've always used the resistor. To date, I haven't had a single problem with it (knocks on wood).
