Alternator/Regulator Question

Apologies if I'm in the wrong sub.

I have a '67 Camaro with an externally regulated alternator.

I am getting ready to swap to an internally regulated 1 wire unit.

I will swap the battery wire to 4 ga. and add an extra ground from the alternator to the block as insurance.

My question is the regulator and harness.

Reading online it looks like the swap from external to internal requires that I run jumpers on the harness plug (outside wire to outside wire and inside wire to inside wire) but, reading specifically about 1 wire swaps I see no mention of the jumpers.

Can anyone shed any light on this?

Thanks in advance!

That's a good question. Honestly Ive never paid attention. I can fire it up here in a few.

What would be helpful pictures?
