    Trying to figure out the right wiring harness from OPGI. 70 GS, 455, auto trans, w/AC and MSD. Any ideas? Attached is a pic of suggestions. Not sure about internal or external regulators...

    First thing I would recommend to you is to buy from ToddsGS right here on V8. Not only are you helping a V8buick guy, but Todd can get you anything you get from other sources, and maybe at better prices.

    Second, you say you want to run an MSD. In that case, you don't want a points resistance wire. The HEI harness will come with a plain wire for the Ignition + connection. That will either hook to the MSD ready to run distributor, OR, it will serve as the turn on lead for the MSD box. In either case, choose the HEI option if you aren't running points.
