1976 2.0. Putting engine back in after a 2056-dectomy, but it has been out too long and as usual I didn't take enough pictures of all the important connections.
There are many threads on wiring for the starter. However, I have one additional wire that I don't see in any of those threads, but I marked as going to the starter solenoid. Wire in my hand:  Way off to right:  Out of focus in center:  The wire in question is red and has a spade terminal on the end. It is not the cable that runs from the alternator. My best guess as of today is that is leads up to the firewall and goes through here:  Thoughts? Car has air conditioning, so is this part of that? |

The amperage is only part of the issue. The Bosch solenoid is 12v and sensitive to it. The Ford solenoid hasn't changed since before your thunderbird and it only needs 6v. So as the wiring gets old and the distance traveled starts hurting it, the Ford doesn't care.
