They have extra wires on the back as the ecu can control them. But im looking for something like that if you have a link?
Im sure you could wire it in tho

I want the ecu control. Turn the altenator off at full throttle for approx 1 victa worth of extra hp

If you turn the alt off you will have low voltage at wot. I used a 40$ vx v6 commodore alt with the evo pulley (modified slightly).

Wont matter for 10 sec at a time...

Grumpy old man from the school of hard knocks
since it appears no one here has given you an answer...there is only one way to find out. try it...
I think that the voltage changes as you switch alt on and off will do funny things to your tune. Delivery of bang juice changes with voltage to the injector, the haltec PS use a table to compensate for this, do the factory ecu's do this? might be a big enough difference at big rpm/ load to make a difference, or at worst, do damage. Your voltage at the injectors will drop about 1 volt without the alt running, worse with a shit battery, lights on,doof box at full noise etc.....
Just a thought.

Yep volt compensation with ecmlink and also on later evo ecu.
I will keep my silly ideas to myself from now on

Not stupid ideas jack, I just didn't know if they did the compensation thing. I only realized a little while ago that my focus dropped the AC at full noise. I learnt the hard way about voltage compensation with the durascort after the volt reg shat itself.
Mate, the pulley is different to suit a different belt, the electronic plug is different to EVO 3 and its mounted in the opposite direction than an EVO 3 (plus spins the opposite direction but don't know if that make a difference).
You will also find that the brown plug in the pic will be facing your block, and the top mounting hole might not be in alignment with where it needs to bolt in when tensioning the belt.
I doubt it will fit.

Agreed↑
Except it spins same way.
Not a bolt on fit
Off load it to me for testing

Sorry my commodore one has a relocation kit and sits on the other side. I can tell you now the difference between 12.7v and 14.5v is huge for fuel pump flow and ignition output. Even 1v makes a big difference for missfires.
