I got an msd 6a, trying to wire it up to my carb'd 307.. HEI mechanical and vacuum advance.. Accel supercoil. dont have adobe so I cant get schematics off of MSD website..
I found an article where they put one on a vette and it told me what the wires are for but im not real sure on how to go about this. 6 wires.. big black and red,, power and ground to box. small orange=coil+ black=coil- red=trigger white is for points, dont use.. any help would be greatly appreciated-Chris

 

call msd, they can guide you over the phone.
