I'm currently running a Mallory Dual Points distributor in my 3.5 with a power amplifier. Until the vacuum advance went out, all seemed to be performing just fine.

I'm trying to decide if I should replace the vacuum advance and leave the points or replace the distributor with a newer electronic distributor.

Interested to hear your thoughts...

Nothing wrong with points. A new vac advance will be WAY less hassle.

The D-90 OEM setup workes good for what it is and is reliable. On the flip side ive installed MSD electronic ignitions in a several older jags and the differences are very clear. They are dead reliable and the high end ones are programmable. The engines start with more "authority".
Smoother starting / running, although i didn't dyno more power accross tye rpm range is felt while driving, better revving etc.. and once installed you'll never have ignition issues again!

What about splitting the difference and doing an electronic conversion kit to my existing distributor?

That is the kit im right referring to. Its bulletproof and works like a charm! Its also feasible and easily done. only other option would be to install cam & crank shaft sensors , a new ecu etc..etc..

can you please provide the part numbers you used for this conversion. Will this work on a NAS '95? We've already upgraded the 3.9 to a 4.6.

Wrong type of vehicle, but my '71 300SEL 6.3 had a dual points system, and it was swapped for a pertronix setup. It does run noticeably better, and the distributor had been recently rebuilt and the timing set on a Sun machine.

Got all the parts today and commenced the conversion to Pertronix Electronic Ignition but ran into a snag that I need some help with.

With the Flame Thrower coil that I got to accompany my electronic ignition, I no longer need the ballast resistor so I disconnected it and now that I am reconnecting, I have an extra wire that I don't know what to do with.

On one side of the ballast resistor, there is a white wire which from the wiring diagram is coming from the ignition switch. That's pretty apparent where it needs to go.

On the other side, there are two white with purple stripes wires. One looks like it goes to the starter solenoid and the other goes to the coil.

In the instructions for the electronic ignition, I need to have the white wire from the ignition switch and the red wire from the pertronix go to the positive side of the coil and the black wire from the pertronix go to the negative side of the coil. What do I do with the white with purple stripe wire that goes to the starter solenoid? I think this wire is no loner needed and can be capped off. I believe the purpose of this wire was to bypass the ballast resistor to provide the coil with the full 12volts, but this isn't needed since the coil is a 12volt coil. Can anyone confirm this?

There is also an amplifier wired into the ignition system that I will need to sort out, but that is for a later time. The previous owner fiddled with that so much that there are 4 different colors of wire connected together to form one wire. The brown wire that comes from the amplifier I believe should go to the negative side of the coil. The red wire that use to go to the condenser I have no idea what I am supposed to do with now or even if the amplifier is needed now that I upgraded.

Your help is greatly appreciated.
