How do I convert from external to internal regulated alternator

I just put a 351M in to a 1979 bronco I got with no motor. The motor has a intenaly regulated alternator on it the the bronco was externally regulated so what I'm wondering is how do I convert to internally regulated. I already have a new plug I got to day just need know were the wires go and wich ones to eliminate
thanks for any help

A 351m never came with a internally regulated alternator(it's too old) so be careful. I am going to assume someone swapped it onto the engine you got.

Next question. What type of internally regulated alternator is it? GM, Ford, aftermarket?

Basically what you will need to do is find the trigger wire/terminal for the alternator you have. Most alternators need a wire from the keyswitch to bring them online to charge, and offline so they don't run the battery down with the key off. This wire on your bronco will be the green/red wire on the original regulator. It will be located on the "s" terminal or the "i" terminal of the regulator, depending on how it was equipped from the factory. And then of course you need to hook up the large output wire to the bat +, and some had a feedback wire also.

It is a ford alternator so I hooked the green and red wire to stator termanal and hooked white and black wire to feild termanal and output to + and no luck it didn't work the only one I didn't touch is the yellow wire with the capistor or what ever it is the one with the two yellow wires in the same teminal they just go to postive so mybe that has to go some were I will mess around a bit more if still nothing I'll go to a 3g I had stator & feild crossed at first so maby I fryed the alternator

You have a regular stock Ford alternator it sounds like. I don't know why you said you had an internal regulator alternator. Here's how to hook it up WITH a external regulator for a Ford. If you do not have a electric choke, the stator terminal has no wire going to it on the alternator.

Just wanted to covert to internally regulated because that's what I had but it's on hold because I'm off to rokonvill saschawin for a few weeks to work then I'm doing a 3g when I get back we got about 8 lights on it a winch and a decent size sterio system so I'm sure we can use the extra power
