alternator/regulator wiring help

abodyjoe. i dont have a ballast resistor so to get the 12v ignition source i used the + side of the coil. from my understanding the blue wire needs to be tied into any power source so i used the coil cause it was the closest source. other than that it is the same as your drawing
winston. i have 3 grounds and the one from engine to firewall is directly to the one of the bolts for the voltage reg.
