1977 aspen se Electronic ecu to Pertronix III full set

[jed_laski]

Hi, i just received new billet pertronix ignitor III with fitting flamethrower coil and wires. I got installed 1406 with airgap already and working on stock ignition (distributor is worn pit).

The question is how to wire it with stock electronic chrysler system? I found out most guides cover going from points to this, not an ecu to pertronix straight 12v i got the diagram but it would help me alot if i qould have the guide what to ditchand what to comnect. Thanks!

It should have come with a wiring diagram. From that you should be able to figure out where it connects and what's redundant.
It looks like the main purpose is to add an electronic ignition to a car that doesn't already have it so you shouldn't need any of the mopar ecu components. Start from scratch.

The pertronix doesn't use a factory ECU or the wiring. Read the instructions that came with your kit.

Basically red wire from ditributor goes to coil plus, black to coil negative. Then a keyed B+ (hot in start and run) goes to coil plus. This will be the blue wire from the ballast. You don't need the ballast so remove it, and splice the wires together. The original ECU,and wiring to it, can be left in place, or removed if you like. They aren't needed anymore.

Think of the eletronic distrubutor like a points style like your instructions show. Only difference is one is electronically switched, the other mechanically with points. Otherwise it's exactly the same, especially wirh an internally mounted module.

I am a bit confused by the wiring diagram you posted though. 1959 Dodge electronic ignition?
