120 amp mancini alternator

[will]

I just got the 120 amp alternator from mancini racing. The alt came with a plug that I can't use and I need to know where to hook up the wiring. I know where the big wire goes, not sure about the field wires. This is on a 68 charger with the upgraded engine wiring harness to use the 4 prong ballast and ecu, with 2 field alt. I'm kinda stumped, I don't wanna bolt this alt on and be on the hook for it. I tried searching, found some info, ust not what Ineed.
The back of the alt has a location for the big wire and two posts. I don't want to burn this car to the ground.

I talked to the right guy at Mancini Racing. These alternators are self regulating so no help necessary. Thanks guys!

No hold on there... .

Look, the plug is only for the 60 amp. Here is how I adapted for my 70 to the factory solid state 2 wire voltage regulator.

I think you talked to the wrong guy.

I just noticed over 4 years of flawless function for me. The car got a mix of daily use and long periods of sitting still while doing body repairs. The only thing to watch is for a weak/discharged battery! This thing will throw 60 amp at idle at a weak battery state of charge and start heating stock wires pretty quickly. I'm doing a "Fleet Upgrade" soon, 8AWG wire to new OER brand ALT gauge that is rated for 60amp then 8AWG back to battery. (Protected by a 60amp fuse.)

Thank you b5blue. I didn't put it in today, just got the engine to fire off. I'm going to hold off on this upgrade until I get some miles on it. Why would they sell a 120 amp alt with all the paperwork for the 60 amp? Makes no sense. I'm just glad I could provide some laughter.

Will actually 4 years ago I was confused also. No instructions so I called and asked about an adapter? They sent me the plug for a 60amp?  Now they may think all Denso use the plug.
