So I've been studying this thread
My situation is I'm about to drop a 99' 1.8 into my 90' 1.6. My 1.6 is a shortnose with the V-Belt pulleys and the alternator isn't charging properly, neither the less, I don't own a NA8 internally regulated alternator nor do I want to buy one.
The 99' engine came with an alternator, of which I need to make a voltage regulator for.
Here's a wiring diagram of a 99 NB.
According to the AbeFM
Hook the BLUE wire to switched(?) " 12v" battery voltage
Hook the GREEN wire to the Grey/Red wire on the alternator, pin 1-O on the factory ECU.
So the blue wire of the VR will be going to white wire which leads to the main fuse block and the blue wire connects to the grey/red wire which goes to the powertrain module.
This is an application for NBs.
Now here is a charging circuit wiring diagram of a 90' NA6.
In this case, the blue wire connects to the white/black wire going to the instrument cluster and the green wire goes to the white wire which leads to the
80A main fuse block right?
