I just restored car and had all wiring out. Did away with ballast resistor. have a 6Al box. Hooked it up the way the wiring diagram told me but car would not hit a lick. called MSD and they told me I needed to hook up the thin red wire to a source that would stay hot at the coil with the key in the start pos. The only thing I found was the starter relay. Did that and as long as I had the key in the start pos. it wanted to hit. When I let off the key it would die. Called them back talked to someone else. He told me I needed to find a source that did that but also another source that would stay hot with key in run position and hook them together that would not interfere with each other. Not possible. Starter wants to stay engaged all the time. According to the wiring diagram from MSD the thin red wire needs to be hooked to a ignition key source. What would be a ignition key source on a 76 Duster. I have changed the steering column from an automatic to a 4 speed column. I have checked the wires coming from the column and have not found any wires that fit the bill. I can find wires that stay hot when the key is on but do I find one that is hot in the start pos. or the run position. I need help bad. Would appreciate someone who can walk me through this problem in detail. I am not a mechanic and confused. Thanks,Bill
 
Not to familiar with you car but in general you could look at alternator excite wire for key " on " power.For " Cranking" voltage look at Starter solenoid for a terminal that powers up during cranking proccess for ignition boost . Find the solenoid terminal ( purple wire maybe ) for cranking voltage on starter solenoid. There should be many places for key " on " voltage . Hope this helps , i am new here and a boat mechanic so i could be way off base here . Maybe at least some one will come on tell you the right method ...lol
 
Is all your wire basically factory? Like did you or anyone take out or change much of the wiring? You should be able to pull the proper power from the ballast input +12v wire. I understand you removed the ballast, but is the wires that are suppose to feed the ballast still there?
 
where you ballast resistor was...there should be a blue and brown wire...connect the msd red wire to those two wires...
