Andrew, that would be the better way, maybe? But, I have the 99 magnum engine and it's water pump, and alternator bracket with the single serpentine system. Therefore, I used the 99 alternator that fits that bracket system. That is an internally controlled alternator. Now the question is whether it needs the cpu or can get by with just the wiring, going to it with the electronic box that mounts on the top of the alternator. Maybe that is all that I need to make it work.



I think you need to show a part number or picture of this 99 internal alt. Mine is a 2000 mag and it was externally regulated. So I am not sure which alt you have, and have never heard of one like that.

For mine, I used the plug coming out and wired it like I would any dual field alt. 2 wires came out. one went to ground, the other went to my vr output.
