Have had the 01 zx2 in the garage for couple weeks started with the halfshaft boot blew then ball joints outer rods wheel bearings. 3rd owner I know of I guess the original did the majority of the modifications I'm sure I'll be getting into some of that later.
Point or question is. I'm running 1000w rms system 0/1 gauge for everything I have a mean green alt for a 92 xj. It's brand new I tore it down cleaned it (it's been sitting a few years) well jeep doesn't use plugs. So I read the book I know what the wires in the zx2 plug do but idk where to put them on the alt. Posted a few questions here and there emailed mean green got nothing. I'm down to a little wiring in the dash and she's ready to go so some help would be glorious

on a 92 xj, it uses the jtec controller, so the pcm controls the field coil by regulating the ground... on an escort, the alt is internally regulated. you would need to externally control the alternator, possibly with something like an old dodge voltage regulator. here is the wiring diagram from the xj. you can see the pcm controls the field pin 20, and asd relay power comes in on pin 57

Hypothetical
If I installed a (devise reading the systems voltage live.) And a switch could I essentially manually regulate when it's charging and shut it off ?
I wanted to install one anyway

The alternator that was on B4 is from a truck. (That's all the info I got oh or maybe a van.) 🙄 The alternator was abandoned threw the winter in the the snow none the less. I have it in pieces still. Nothing seemed interchangeable.

Most expensive parts n work cheaper. Lolol awesome!

thats not how it works. the regulator works in real time, switches thousands of times per second to maintain the charge voltage. basically what the regulator does is short the field coil to ground, lowering the voltage. that is the function of the charge controller/internal regulator. there is no way you can manually 'switch' it, unless your brain and hands could monitor and switch about 5,000 times a second. you could hook up a voltage regulator from like a first gen dodge truck, or a ramcharger. that would be the 'easiest' way. other than that, your going to have to restart and find a purpose built setup. as far as the focus,,... no idea.

Ahhh gotcha. Thanks for helping me understand that. I know a guy with a couple older dodge trucks . Trying to trade this one for said purpose built high output one. No takers :/
The focus alternator is only missing the orange wire that goes from the alts plug to the alt. Researching
