Wiring harness advice

Thanks for all the information and pointers guys, it's very much appreciated! Have a lot to ponder about which route I want to go. I'm going to give M&H a shout and confirm with them exactly what their 69 harness setup for electronic ignition is.

As much as it is more expensive, I did contact Evan's too, and he has confirmed that his engine&forward light harness for the 1969 Dart is set up for the 1969 and older style regulator and alternator, and has the direct connection for a Mopar orange box.

I'll see what M&H has to say and post back, if anyone's interested.
