hi, 1991 s5 6port turbo ms3x. I think im having trouble with my idiot light cluster cutting in and out and it seems like when it fails the alternator also quits charging.. seeing as ive already built and wrapped my harness id like to avoid running more wires to the engine bay, is it possible to use megasquirts “high speed feedback field control” on the w/b wire from the cluster? And maybe use the warning lamp output from the ms to run the charge light there? Any help is appreciated ive been learning as i go
