External voltage regulator

Hey, I have an external voltage regulator for my new ho alternator. My question is, I need to wire the voltage regulator to the +12 ign relay and I have no clue how to get to it or anything like that. Would it be easier just to run the wire through the firewall and use the ign switch? I have a 99 ford ranger. thanks!

if the ignition relay is the same thing as the starter relay it is usually the first thing in line if you follow the (+) away from the battery. Mine is a cylindrical looking thing with two copper studs on top.

By your instructions it sounds like you need to connect to the stud closest to the battery.

No, the ignition relay that turns on everything in the car when the ign switch is on
