hi,
working on my 1975, 2.0, 5spd.
i had the engine/trans out and i'm in the process of installing it.
although i took time to label all the wires, one got lost in the mix. its the red wire from the alternator. i thought it was for the stater but it now won't reach and i'm also not sure which terminal on the starter is correct.

The thick red wire with a ring terminal goes to the threaded post on the starter. If it doesn't reach double check your routing.

Thanks!

Sorry i should have asked, it shares the post with the battery wire?

Yes, they share that post.

The alternator charges the battery via the starter cable, hence it shares the post.
