'67 Dart GT wiring question

I "need" to rewire my Dart. The previous owner was not electrically incline. As it sits now, while driving, when I hit the brakes, the brake lights do come on... but so do the front turn signals and fender mounted signal indicators as well. No turn signals, no interior or dash lights.

That said, the car started life as a 273 six banger. It now has a very well built 340. It was pretty much stripped of any creature comforts to be a drag racer. My goal is to get it "somewhat" street-able again.

My dilemma is which harness to get. I actually think a '67 273 harness would be fine as the only electrical connections (that I can think of) to the motor are the starter and alternator, all else should be the same.

Any input would be appreciated.
