problems with engine/light harness after msd installed

[440turner]

  I have a 67 Barracuda that I put a 440 in and switched to an all MSD ignition with a 6al, blaster coil, pro-billet dist., and wires. I now am trying to get my head lights to work or any instrument lighting and cannot. I show power in the sockets of my headlights, but cannot light the bulbs. I do not have any power at the instrument fuse holder in the fuse box. I must have not used a ground out of the front harness and or didnt hook up a power wire somwhere. I basically have used no wires from the old front harness and all my doubt seems to point in that direction, have I overlooked something in the old harness that needs to be reconnected.The headlights are brand new halogens from the auto parts store. I also have installed a Chrysler dual output alt. with the external regulator. I am going out to the garage to work on this for the next three days and all the help I could get would be appreciated.

it sounds like your headlights are not grounded.hard to say without being there

 You are correct, I worked on the car all day and got most of my lights working, but still have no power to the instrument lighting fuse in the fuse box. Im going back at it tommorrow to try and get the rest of it squared away.
