I'm generally familiar with the brown-out condition the Z's ran under due to an undersized alternator or so it was explained to me when I replaced my headlight switch assembly..

I was talking about a different problem. You'll know it if it happens.

On the loose pins, if it was mine I might put a slight twist on every male pin in the ECU. Increasing effective width. I'd have to check the contact points to be sure it would work though.

On to the next problem. Might as well get ready for the failing ignition module. It's a high probability.

Oh? Do you mean above and beyond burning out the internals on the selector and high-beams swtiches? Do you think this is something to be concerned about now that my power draw has been dropped so much?

GENIUS. I was literally just now chatting with my wife about how I can either make the female sides more grabby, or the male sides "fatter". Did not think of twisting to accomplish this. I will keep that one in the arsenal, thanks! Now I just need to get the harness connector disassembled and verify root cause.

I already have a spare...which might actually be in the car now (ref. prior comment somewhere). I had an unrelated issue several years ago and put in a new one but the old one tested out great. Uncertain which is in the car now. If I remember I'll open the box in my parts bin and see who's hiding in there.
